An Atom-Economic and Stereospecific Access to Trisubstituted Olefins through Enyne Cross Metathesis Followed by 1,4-Hydrogenation was written by Ratsch, Friederike;Schmalz, Hans-Guenther. And the article was included in Synlett in 2018.Application In Synthesis of 3,7-Dimethyloctan-1-ol The following contents are mentioned in the article:

The combination of intermol. enyne cross metathesis and subsequent 1,4-hydrogenation opens a stereocontrolled and atom-economic access to trisubstituted olefins. By investigating different combinations of functionalized alkyne and alkene substrates, it was found that the outcome (yield, E/Z ratio) of the Grubbs II-catalyzed enyne cross-metathesis step depends on the substrate’s structure, the amount of the alkene (used in excess), and the (optional) presence of ethylene. In any case, the 1,4-hydrogenation, catalyzed by 1,2-dimethoxybenzene-Cr(CO)₃, proceeds stereospecifically to yield exclusively the E-products from both the E-and Z-1,3-diene intermediates obtained by metathesis. A rather broad scope and functional group compatibility of the method is demonstrated by means of 15 examples. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Application In Synthesis of 3,7-Dimethyloctan-1-ol).

3,7-Dimethyloctan-1-ol (cas: 106-21-8) 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. 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.Application In Synthesis of 3,7-Dimethyloctan-1-ol

Evaluation of HIV-1 inhibition by stereoisomers and analogues of the sesquiterpenoid hydroquinone peyssonol A was written by Treitler, Daniel S.;Li, Zhufang;Krystal, Mark;Meanwell, Nicholas A.;Snyder, Scott A.. And the article was included in Bioorganic & Medicinal Chemistry Letters in 2013.Name: 2,5-Dihydroxy-4-methylbenzaldehyde The following contents are mentioned in the article:

Peyssonol A, a brominated natural product with documented anti-HIV-1 activity, was synthesized racemically along with 6 isomers and 15 truncated analogs and synthetic precursors. These compounds were screened in a cell-based assay against a recombinant HIV-1 strain to investigate structure-activity relationships. The results obtained suggest that both the aliphatic and aromatic domains of peyssonol A are responsible for its potency, while the stereochem. configuration of the substituents on the aliphatic domain, including their bromine atom, are largely irrelevant. Although none of the analogs tested were as potent as the parent natural product, several exhibited greater therapeutic indexes due to reduced cytotoxicity, noting that nearly all compounds tested were measurably cytotoxic. This study involved multiple reactions and reactants, such as 2,5-Dihydroxy-4-methylbenzaldehyde (cas: 52010-89-6Name: 2,5-Dihydroxy-4-methylbenzaldehyde).

2,5-Dihydroxy-4-methylbenzaldehyde (cas: 52010-89-6) 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. 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.Name: 2,5-Dihydroxy-4-methylbenzaldehyde

Polyurethane polyols (PUPOs) and melamine polyols (MEPOs), invented by AkzoNobel Coatings, offer valuable alternatives to the commonly used polyester and acrylic polyols and new formulating tools for the development of novel coatings. The resin chem. is based on the predominantly selective reactivity of α,β- and α,γ-diols with commonly used polyisocyanate and melamine formaldehyde crosslinkers. The resulting low mol. weight, hydroxyl functional resins are suitable for use in low VOC coatings. By choosing the appropriate crosslinker, diol, and modifier, the chem. structures of these resins can be altered to obtain the desired properties of the coatings. Synthesis methods for novel PUPOs and MEPOs and properties of one component and two component coatings containing them are described.

2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4) 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. 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.Computed Properties of C9H20O2

Novel aliphatic enzymically degradable polyesters with short alkyl side chains for tuning crystallinity are presented in this work. The intrinsic problem of aliphatic polyesters is their brittleness and tendency to crystallize. This was modulated by the synthesis of random copolyesters based on aliphatic linear monomers, adipic acid, 1,5-pentanediol and monomers with aliphatic branches, such as 2-butyl-2-ethyl-1,3-propanediol by polycondensation. The resulting copolyesters were crystalline, wax-like or had liquid texture with varied mech. properties and enzymic degradability depending upon the copolymer composition Such polyesters are of significant interest for a wide range of possible applications such as controlled drug delivery, agricultural applications and as packing materials.

δ-C-H Mono- and Dihalogenation of Alcohols was written by Herron, Alastair N.;Liu, Dongxin;Xia, Guoqin;Yu, Jin-Quan. And the article was included in Journal of the American Chemical Society in 2020.Recommanded Product: 3,7-Dimethyloctan-1-ol The following contents are mentioned in the article:

Alkoxy radicals have long been known to enable remote C-H functionalization via 1,5-hydrogen atom abstraction. However, methods for their generation traditionally have relied upon highly oxidizing metals, UV radiation, or preformed peroxide intermediates, which has prevented the development of many desirable transformations. Herein we report a new bench-stable precursor that decomposes to free alkoxy radicals via a previously unreported single-electron oxidation pathway. This new precursor enables the fluorination and chlorination of remote C-H bonds under exceptionally mild conditions with exceedingly high monoselectivity. Iterative use of this precursor enables the introduction of a second halogen atom, granting access to remote dihalide motifs, including CF₂ and CFCl. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Recommanded Product: 3,7-Dimethyloctan-1-ol).

Citral-to-Menthol Transformations in a Continuous Reactor over Ni/Mesoporous Aluminosilicate Extrudates Containing a Sepiolite Clay Binder was written by Simakova, Irina L.;Vajglova, Zuzana;Maki-Arvela, Paivi;Eranen, Kari;Hupa, Leena;Peurla, Markus;Makila, Ermei M.;Warna, Johan;Murzin, Dmitry Yu.. And the article was included in Organic Process Research & Development in 2022.Recommanded Product: 106-21-8 The following contents are mentioned in the article:

One-pot continuous synthesis of menthols from citral was performed over 5 wt % Ni supported on a mesoporous aluminosilicate catalyst with sepiolite as a binder at 70°C with a selectivity of 75% to menthols. Catalyst deactivation with time-onstream resulted in a decrease of the conversion and selectivity to menthol at the expense of higher selectivity to isopulegols. Stereoselectivity to isopulegols and menthols only slightly changed with conversion and TOS. A kinetic model capable of describing exptl. data for transformations of citral to menthol in a continuous mode was developed. It was based on a detailed reaction network and also comprised deactivation on both metal and acid sites. Numerical data fitting confirmed a good correspondence between the exptl. data and calculations This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Recommanded Product: 106-21-8).

And the article was included in Journal of Applied Polymer Science in 2005.Computed Properties of C9H20O2 The following contents are mentioned in the article:

A series of glycol dibenzoates was synthesized by transesterification of glycols with Me benzoate. PVC films were prepared from suspension grade PVC and the dibenzoates at a constant content of the dibenzoates. The mech. properties of the films were measured. In addition, the extractability and the absorption of various liquids was determined The effect of the structure of the glycol component in the dibenzoates on the mech. properties of the films and the plasticizing efficiency was investigated. Neopentyl glycol dibenzoate exhibits the highest plasticizing effect, followed by triethylene and ethylene glycol dibenzoates and the 2-(n-butyl)-2-ethyl-1,3-propanediol derivative It was found that the ether linkages in the dibenzoates mainly contribute to the plasticization of PVC.
