Herein, the study reported extraordinary chemoselective reduction with selectivity (>99%) by the catalytic transfer hydrogenation of various α,β-unsaturatedketones with a catalyst of NiPd alloy nanoparticles decorated on mesoporous graphitic carbon nitride (NiPd/mpg-C3N4) under mild conditions in a water/methanol medium. NiPd alloy NPs were synthesized by the reduction of metal salts in oleylamine
本文中,研究报告称,通过在介孔石墨氮化碳上装饰NiPd合金纳米粒子的催化剂(NiPd / mpg-C 3 N 4)催化转移各种α,β-不饱和酮,可实现非凡的化学选择性还原(> 99%)。)在水/甲醇介质中的温和条件下。通过在硼烷-叔丁胺的帮助下在油胺(OAm)溶液中还原金属盐,合成NiPd合金NP ,然后通过液相自组装法在mpg-C 3 N 4上修饰。通过TEM,XRD和ICP-MS对NiPd / mpg-C 3 N 4纳米催化剂进行了表征。NiPd / mpg-C 3 N4纳米催化剂是用于化学选择性还原α,β-不饱和酮的高活性催化剂,所有有机化合物均以高收率和99%的选择性转化。另外,该催化剂可以重复使用五次而不会显着降低反应产率。
Design, synthesis and anticholinergic properties of novel α-benzyl dopamine, tyramine, and phenethylamine derivatives
Due to the important biological properties of dopamine, phenethylamine, and tyramine derivatives in the central nervous system, herein the synthesis of novel α-benzyl dopamine, phenethylamine, and tyramine derivatives is described. The title compounds were synthesized starting from 3-phenylpropanoic acids and methoxybenzenes in six or seven steps. Firstly, 3-(2,3-dimethoxyphenyl)propanoic acid (11)

Synthesis and activity of a new series of chalcones as aldose reductase inhibitors
A new series of chalcone derivatives has been synthesized and tested in vitro in order to assess their ability to inhibit aldose reductase enzyme (ALR2) and their specificity towards the target enzyme with respect to other oxidoreductases, such as aldehyde reductase, sorbitol dehydrogenase, and glutathione reductase. All the compounds display affinity for ALR2. The X-ray crystal structure of 1-(2,4-dihydroxyphenyl)-3-(2-methoxyphenyl)propen-1-one was determined. (C) Elsevier, Paris.
