Kawawaki, Tokuhisa published the artcileCreation of High-Performance Heterogeneous Photocatalysts by Controlling Ligand Desorption and Particle Size of Gold Nanocluster, Name: 2-Phenylethanethiol, the publication is Angewandte Chemie, International Edition (2021), 60(39), 21340-21350, database is CAplus and MEDLINE.

Recently, the creation of new heterogeneous catalysts using the unique electronic/geometric structures of small metal nanoclusters (NCs) has received considerable attention. However, to achieve this, it is extremely important to establish methods to remove the ligands from ligand-protected metal NCs while preventing the aggregation of metal NCs. In this study, the ligand-desorption process during calcination was followed for metal-oxide-supported 2-phenylethanethiolate-protected gold (Au) 25-atom metal NCs using five exptl. techniques. The results clearly demonstrate that the ligand-desorption process consists of ligand dissociation on the surface of the metal NCs, adsorption of the generated compounds on the support and desorption of the compounds from the support, and the temperatures at which these processes occurred were elucidated. Based on the obtained knowledge, we established a method to form a metal-oxide layer on the surface of Au NCs while preventing their aggregation, thereby succeeding in creating a water-splitting photocatalyst with high activity and stability.

Nishimura, Takahiro published the artcileRhodium-catalyzed aryl transfer from trisubstituted aryl methanols to α,β-unsaturated carbonyl compounds, Recommanded Product: 9-Phenyl-9H-xanthen-9-ol, the publication is Angewandte Chemie, International Edition (2007), 46(26), 4937-4939, database is CAplus and MEDLINE.

The rhodium-catalyzed arylation of α,β-unsaturated carbonyl compounds with 9-aryl-10-benzyl-9,10-dihydroacridin-9-ols as arylating reagents proceeds efficiently via β-aryl elimination of the rhodium alkoxide intermediates, to give the 1,4-addition products in high yields. E.g., reaction of MeCOCH:CHC₅H₁₁ with 9-phenyl-10-benzyl-9,10-dihydroacridin-9-ol gave 96% MeCOCH₂CHPhC₅H₁₁.

Manna, Cesar M. published the artcileStereoselective Catalysis Achieved through in Situ Desymmetrization of an Achiral Iron Catalyst Precursor, Synthetic Route of 597-52-4, the publication is Journal of the American Chemical Society (2015), 137(45), 14232-14235, database is CAplus and MEDLINE.

Stereoselective catalysis proceeds with catalyst control but without the need to synthesize preformed chiral catalysts or ligands. Fe-based catalysts were discovered to effect the stereoselective polymerization of lactides starting from a single achiral precursor and the proper choice of an achiral silanol additive. Spectroscopic anal. of the polymer revealed that the stereoselectivity originates from an enantiomorphic site rather than a chain end stereocontrol mechanism. Fe intermediates that are stereogenic at Fe probably form in situ as a result of desymmetrization that occurs from a change in the metal coordination number The proposed mechanism is supported by a combination of spectroscopic measurements, model complexes, kinetic measurements, and DFT calculations

A review. Ambroxyl is a Mucolytic expectorant. Ambroxyl has short half life (3- 4hrs) makes the development of sustained release forms extremely advantageous, Ambroxyl is a weak acidic pka 4.5 – 6, it has pH dependent solubility, characterized in low pH condition present in stomach, Which consequently delayed in onset of action, Formulation of SR tablet is effective approach for mucolytic expectorant it gives maximum action with prolong drug concentration due to sustained release from tablet matrix. Different formulation (F1 – F7) designed with HPMC K100, HPMC 5CPS, Povidone K30, MCCP. pre and post -compression parameters for all formulation were studied.

Afanasenko, Anastasiia published the artcileA One-Pot Approach for Bio-Based Arylamines via a Combined Photooxidative Dearomatization-Rearomatization Strategy, Quality Control of 645-56-7, the publication is Chemistry – A European Journal (2022), 28(34), e202200309, database is CAplus and MEDLINE.

The synthesis of arylamines from renewable resources under mild reaction conditions is highly desired for the sustainability of the chem. industry, where the production of hazardous waste is a prime concern. However, to date, there are very few tools in chemists’ toolboxes that are able to produce arylamines in a sustainable manner. Herein, a robust one-pot approach for constructing bio-based arylamines via a combined photooxidative dearomatization-rearomatization strategy is presented. The developed methodol. enables the synthesis of structurally complex amines in moderate-to-good isolated yields using biomass-derived phenols, natural α-amino acids, and naphthols under remarkably mild reaction conditions. For the photooxygenation of phenols, a novel chrysazine-based catalyst system was introduced, demonstrating its efficiency for the synthesis of natural products – hallerone, rengyolone, and the pharmaceutically relevant prodrug DHED (10β-hydroxy-17β-hydroxyestra-1,4-dien-3-one).

Sakurai, Shuhei published the artcileStructure-antioxidant activity (oxygen radical absorbance capacity) relationships of phenolic compounds, Name: 3-Hydroxyphenylacetic acid, the publication is Structural Chemistry (2022), 33(4), 1055-1062, database is CAplus.

Antioxidant capacity is the extent to which a compound can eliminate reactive oxygen species, and in vitro methods for its chem. evaluation have been proposed. Among these methods, the oxygen radical absorbance capacity (ORAC) assay comes close to the oxidation reaction in the living body because it generates radical species that mimic the lipid peroxyl radical involved in the peroxidation reaction of biol. components and react in a phosphate buffer. In this study, PM7, a semi-empirical MO method, was used to calculate the thermodn. properties (bond dissociation enthalpy, ionisation potential and proton affinity) associated with ORAC. We also applied the clusterwise linear regression anal. as a statistical method for grouping the antioxidants by structure. By analyzing the data for antioxidants, the trend in the hydrophilic ORAC values was determined using the calculated structures and bond dissociation enthalpies of the groups classified according to the presence or absence of oxygen functional groups in the ortho position of phenol. Further studies of indicators other than bond dissociation enthalpy are needed to predict the ORAC of other antioxidants such as flavonoids and indoles.
