Hydrosilyl Group-directed Iridium-catalyzed peri-Selective CH Borylation of Ring-fused (Hetero)Arenes

The iridium-catalyzed direct CH borylation of ring-fused (hetero)arenes afforded borylated products in a peri-selective manner, directed by a proximal hydrosilyl group. Further selective transformations of the boryl and silyl groups enabled the synthesis of various multisubstituted (hetero)arenes, such as 1,8-disubstituted naphthalenes and 3,4-diarylindole.

Biphenyl-based diaminophosphine oxides as air-stable preligands for the nickel-catalyzed kumada-tamao-corriu coupling of deactivated aryl chlorides, fluorides, and tosylates

A cooperative couple: Cooperative bimetallic activation of C-F and C-O bonds gave rise to easy coupling with aryl fluorides and tosylates. Novel air- and moisture-stable diaminophosphine oxides derived from 1,1?-biphenyl-2, 2?-diamine proved to be versatile preligands for the nickel-catalyzed cross-coupling of aryl Grignard reagents with a variety of deactivated aryl chlorides, fluorides, and tosylates (see scheme).

Catalytic asymmetric hydrogenation of imines with a chiral titanocene catalyst: Scope and limitations

The asymmetric hydrogenation of imines with a chiral titanocene catalyst derived from Brintzinger’s ansatitanocene complex 1 proceeds to afford amines with good to excellent enantioselectivity. The catalyst is particularly effective for the reduction of cyclic imines. For these substrates enantiomeric excesses from 95 to 99% were achieved. For acyclic imines lower enantiomeric excesses were observed. The reason for this is likely due to the fact that the acyclic imines are mixtures of anti and syn isomers which interconvert during the reaction. The catalyst was found to be tolerant of many functional groups found in organic synthesis. Thus the reaction represents an effective method for the synthesis of chiral cyclic amines.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 4721-98-6 is helpful to your research. Electric Literature of 4721-98-6

Design and synthesis of piperazinylpyridine derivatives as novel 5-HT 1A agonists/5-HT3 antagonists for the treatment of irritable bowel syndrome (IBS)

We have prepared a series of piperazinylpyridine derivatives for the treatment of irritable bowel syndrome (IBS). These compounds, which were designed by pharmacophore analysis, bind to both serotonin subtype 1A (5-HT 1A) and subtype 3 (5-HT3) receptors. The nitrogen atom of the isoquinoline, a methoxy group and piper-azine were essential to the pharmacophore for binding to these receptors. We also synthesized furo- and thienopyridine derivatives according to structure-activity relationship analyses. Compound 17c (TZB-20810) had high affinities to these receptors and exhibited 5-HT1A agonistic activity and 5-HT3 antagonistic activity concurrently, and is a promising drug for further development in the treatment of IBS.

Gold Particles Supported on Amino-Functionalized Silica Catalyze Transfer Hydrogenation of N-Heterocyclic Compounds

In this work we demonstrate that exceptionally small gold particles (d=0.6¡À0.2 nm) supported on amino-functionalized mesoporous silicate SBA-15 are highly active in transfer hydrogenation of structurally diverse unsaturated N-heterocyclic compounds. The heterocyclic ring is reduced selectively. The gold particles aggregate to a diameter of 4?5 nm in the presence of formic acid/triethylamine (hydrogen donor) during the first catalytic run. In subsequent cycles the nanoparticles maintain their size, yielding a very stable catalytic system that was recycled more than five times. In contrast, analogous SBA catalysts featuring larger (?5?35 nm) gold particles are not active. Excess formic acid also leads to the formation of formamide derivatives of the products of hydrogenation, which can be deformylated quantitatively. Fifteen structurally different substrates, including the scaffolds of quinoline, isoquinoline, quinoxaline, acridine, phenanthroline, quinazoline, and phenanthridine are hydrogenated and deformylated to give the amine products in >90% overall yield. Deuterium labeling experiments indicate that 1,2-addition with subsequent disproportionation of the formed intermediate is the preferred reaction path over the 1,4-addition one, suggesting the participation of a gold hydride species. (Figure presented.).
