Propylphosphonic anhydride (T3P) catalyzed one-pot synthesis of α-aminonitriles was written by Reddy, Sirigireddy Sudharsan;Reddy, Bhoomireddy Rajendra Prasad;Reddy, Peddiahgari Vasu Govardhana. And the article was included in Chinese Chemical Letters in 2015.Electric Literature of C8H8O2 This article mentions the following:

The Strecker reaction was performed via a one-pot three component condensation of heteroaromatic/aromatic aldehydes, secondary amines and trimethylsilyl cyanide in the presence of propylphosphonic anhydride (T3P) to accomplish the corresponding α-aminonitriles. The main advantages of this method are very short reaction time and excellent yields. In the experiment, the researchers used many compounds, for example, 3-Hydroxy-5-methylbenzaldehyde (cas: 60549-26-0Electric Literature of C8H8O2).

3-Hydroxy-5-methylbenzaldehyde (cas: 60549-26-0) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Electric Literature of C8H8O2

Capillary gas chromatographic separation performances of a tetraphenyl porphyrin stationary phase was written by Yan, Yuan;Wang, Zhenzhong;Zhang, Zitong;He, Zhen;Luo, Lun;Fan, Jing. And the article was included in Frontiers in Chemistry (Lausanne, Switzerland) in 2022.Formula: C10H20O This article mentions the following:

Tetra-Ph porphyrin (TPP) has enormous potential for use as gas chromatog. stationary phases because it has a distinctive extended π-π conjugated coplanar structure and a range of interesting properties such as a good solubility in dichloromethane, high m.p., and good thermal stability. In this work, a TPP column was successfully prepared using a static method. The column was nonpolar and had a high efficiency. The chromatog. selectivity of the TPP column was assessed. The TPP column showed superiority retention and higher resolution for alicyclic, aromatic mols. through ring matching and π-π stacking interaction comparable to HP-5MS column. The unique mechanisms through which the TPP column retained polychlorinated biphenyls allowed the peak pair of 2,2′,5-trichlorobiphenyl and 4,4′-dichlorobiphenyl to be resolved better on the TPP column than the HP-5MS column. The TPP column was thermally stable even at 260°C for 2 h and gave results of a high degree of precision (run-to-run and column-to-column) with relative standard deviations <0.05% and <4.96%, resp. The results indicated that porphyrin derivatives will be useful gas chromatog. stationary phases. In the experiment, the researchers used many compounds, for example, (1R,2S,5R)-2-Isopropyl-5-methylcyclohexanol (cas: 2216-51-5Formula: C10H20O).

(1R,2S,5R)-2-Isopropyl-5-methylcyclohexanol (cas: 2216-51-5) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Formula: C10H20O

Srinivasa;Talwar, Rashmi;Venkatesham, B.;Balasubrahmanyam, D.;Kannan, M.;Srinivas, P.;Kumar, K. Shiva;Devi, B. Neelima;Jadhav, Vikram P.;Khan, Sanjoy K.;Mohan, Priya;Chaudhury, Hira;Bhuniya, Debnath;Iqbal, Javed;Chakrabarti, Ranjan. And the article was included in Bioorganic & Medicinal Chemistry Letters in 2011.Product Details of 42514-50-1 This article mentions the following:

The synthesis and biol. evaluation of novel pyrazole-3-carboxamide derivatives, e.g. I, as CB1 antagonists are described. As a part of eastern amide SAR, various chem. diverse motifs were introduced. In general, a range of modifications were well tolerated. Several mols. with high polar surface area were also identified as potent CB1 receptor antagonists. The in vivo proof of principle for weight loss is exemplified with a lead compound from this series. In the experiment, the researchers used many compounds, for example, 3-Amino-3-methylbutan-1-ol (cas: 42514-50-1Product Details of 42514-50-1).

3-Amino-3-methylbutan-1-ol (cas: 42514-50-1) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Product Details of 42514-50-1

Towards a New Generation of Potential Antipsychotic Agents Combining D₂ and 5-HT_1A Receptor Activities was written by Cuisiat, Stephane;Bourdiol, Nathalie;Lacharme, Vincent;Newman-Tancredi, Adrian;Colpaert, Francis;Vacher, Bernard. And the article was included in Journal of Medicinal Chemistry in 2007.Reference of 69393-72-2 This article mentions the following:

We report the discovery and the synthesis of novel, potential antipsychotic compounds combining potent dopamine D₂ receptor antagonist and serotonin 5-HT_1A receptor agonist properties in the same mol. We describe the structure-activity relationship that lead us to the promising derivative: N-[(2,2-dimethyl-2,3-dihydro-benzofuran-7-yloxy)ethyl]-3-(cyclopent-1-enyl)-benzylamine 16. The latter has high affinity for D₂ and 5-HT_1A receptors, whereas it possesses only a weak affinity for 5-HT_2A sites. In cellular models of signal transduction, 16 behaves as a silent antagonist at rD₂ receptors while activating h5-HT_1A receptors with an efficacy at least equivalent to that of the prototypical 5-HT_1A agonist (±)-8-OH-DPAT. These dual actions confer a unique pharmacol. profile to the product. In a behavioral model predictive of pos. symptoms, 16 has an activity comparable to that of the typical antipsychotic haloperidol, while it is devoid of cataleptogenic effects. Although it produces behaviors characteristic of 5-HT_1A receptor activation in rats, these occur at doses 100 times higher than those with (±)-8-OH-DPAT. We believe that the relative balance of D₂ and 5-HT_1A actions in 16 is appropriate, possibly optimal, to ensure superior efficacy and tolerability over existing antipsychotic drugs. In the experiment, the researchers used many compounds, for example, Benzo[d][1,3]dioxol-4-ol (cas: 69393-72-2Reference of 69393-72-2).

Benzo[d][1,3]dioxol-4-ol (cas: 69393-72-2) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Reference of 69393-72-2

Extraction of flavonoids from Glycyrrhiza residues using deep eutectic solvents and its molecular mechanism was written by Yu, Qiang;Wang, Fan;Jian, Yating;Chernyshev, Victor M.;Zhang, Yu;Wang, Zhongming;Yuan, Zhenhong;Chen, Xiaoyan. And the article was included in Journal of Molecular Liquids in 2022.Electric Literature of C10H20O This article mentions the following:

The re-extraction of bioactive compounds from Chinese herb residues is significant for the maximum utilization of biomass resources. However, conventional alc. and aqueous solvents are unsuitable for recovering those compounds In this study, 14 deep eutectic solvents (DESs) were used to improve the efficiency of flavonoid extraction from Glycyrrhiza residues. The maximal total extraction rate (10.68 mg/g) for four flavonoids (liquiritin, isoliquiritin, liquiritigenin, and isoliquiritigenin) was achieved using choline chloride-glycolic acid as the DES under optimal conditions. The extraction rate was 83.03% higher than that by 60% ethanol, a traditional solvent. Anal. of the associated mol. mechanism based on d. functional theory showed that interactions between the solvent and liquiritin were dominated by hydrogen bonds followed by Van der Waals forces, whereas the bonding between the solvent and liquiritigenin only involved Van der Waals forces, thereby verifying the significance of the strength of hydrogen bonding in the DES-flavonoid extraction process. In the experiment, the researchers used many compounds, for example, (1R,2S,5R)-2-Isopropyl-5-methylcyclohexanol (cas: 2216-51-5Electric Literature of C10H20O).

(1R,2S,5R)-2-Isopropyl-5-methylcyclohexanol (cas: 2216-51-5) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Electric Literature of C10H20O

One-Pot Synthesis of B-Ring Ortho-Hydroxylated Sappanin-Type Homoisoflavonoids was written by Mrug, Galyna P.;Myshko, Nataliia V.;Bondarenko, Svitlana P.;Sviripa, Vitaliy M.;Frasinyuk, Mykhaylo S.. And the article was included in Journal of Organic Chemistry in 2019.Synthetic Route of C7H6O3 This article mentions the following:

A reliable method for the synthesis of B-ring hydroxylated homoisoflavonoids (e.g. I) and 3-hetarylmethyl chromones has been developed. The method involves an initial oxa-Diels-Alder reaction of ortho-quinone methides generated from aryl/hetaryl-substituted ortho-(N,N-dimethylaminomethyl)phenols with (2E)-3-(N,N-dimethylamino)-1-(2-hydroxyphenyl)prop-2-en-1-ones and the subsequent cascade of reactions. This synthetic strategy avoids conventional multistep protocols and does not require the protection of hydroxyl groups, thus allowing the facile synthesis of a library of various aromatic and heterocyclic analogs of naturally occurring homoisoflavonoids. In the experiment, the researchers used many compounds, for example, Benzo[d][1,3]dioxol-4-ol (cas: 69393-72-2Synthetic Route of C7H6O3).

Benzo[d][1,3]dioxol-4-ol (cas: 69393-72-2) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Synthetic Route of C7H6O3

ACe inhibitory and antihypertensive activities of wine lees and relationship among bioactivity and phenolic profile was written by Lopez-Fernandez-Sobrino, Raul;Soliz-Rueda, Jorge R.;Margalef, Maria;Arola-Arnal, Anna;Suarez, Manuel;Bravo, Francisca I.;Muguerza, Begona. And the article was included in Nutrients in 2021.Recommanded Product: 10083-24-6 This article mentions the following:

Wine lees (WL) are byproducts generated in the winemaking process. The aim of this study was to investigate the angiotensin-converting enzyme inhibitory (ACEi) activity, and the blood pressure (BP) lowering effect of WL from individual grape varieties. The relationship among their activities and phenolic profiles was also studied. Three WL, from Cabernet, Mazuela, and Garnacha grape varieties, were firstly selected based on their ACEi properties. Their phenolic profiles were fully characterized by UHPLC-ESI-Q-TOF-MS. Then, their potential antihypertensive effects were evaluated in spontaneously hypertensive rats (SHR). BP was recorded before and after their oral administrations (2, 4, 6, 8, 24, and 48 h) at a dose of 5 mL/kg bw. Cabernet WL (CWL) exhibited a potent antihypertensive activity, similar to that obtained with the drug Captopril. This BP-lowering effect was related to the high amount of anthocyanins and flavanols present in these lees. In addition, a potential hypotensive effect of CWL was discarded in normotensive Wistar-Kyoto rats. Finally, the ACEi and antihypertensive activities of CWL coming from a different harvest were confirmed. Our results suggest the potential of CWL for controlling arterial BP, opening the door to com. use within the wine industry. In the experiment, the researchers used many compounds, for example, (E)-4-(3,5-Dihydroxystyryl)benzene-1,2-diol (cas: 10083-24-6Recommanded Product: 10083-24-6).

(E)-4-(3,5-Dihydroxystyryl)benzene-1,2-diol (cas: 10083-24-6) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Recommanded Product: 10083-24-6

Growth of p-Type Tin(II) Monoxide Thin Films by Atomic Layer Deposition from Bis(1-dimethylamino-2-methyl-2propoxy)tin and H₂O was written by Han, Jeong Hwan;Chung, Yoon Jang;Park, Bo Keun;Kim, Seong Keun;Kim, Hyo-Suk;Kim, Chang Gyoun;Chung, Taek-Mo. And the article was included in Chemistry of Materials in 2014.Related Products of 14123-48-9 This article mentions the following:

A reliable at. layer deposition (ALD) scheme to fabricate p-type Sn monoxide (SnO) films at 90-210 oC is presented for the 1st time using the Sn(II) precursor, bis(1-dimethylamino-2-methyl-2-propoxy)tin, and H₂O. The self-limiting features of the SnO ALD process could clearly be observed under wide process conditions. The growth per cycle of the SnO ALD films were varied from 0.61 to 0.08 Å/cycle as the growth temperature was increased from 90 to 210°, and the O/Sn at. composition ratio of ∼1.2 was maintained at all studied temperatures Amorphous and crystalline SnO films were obtained at 90-120° and 150-210°, resp. The deposited SnO films exhibited p-type conductivity with Hall mobility values of 0.4-2.9 cm²/V•s. The carrier concentration and resistivity are in the range of 3.4×1017-1.6×1018 cm^-3 and 4.9-14.5 Ω•cm, resp. In the experiment, the researchers used many compounds, for example, 1-(Dimethylamino)-2-methylpropan-2-ol (cas: 14123-48-9Related Products of 14123-48-9).

1-(Dimethylamino)-2-methylpropan-2-ol (cas: 14123-48-9) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Related Products of 14123-48-9
