2-Mercaptoimidazoles, a new class of potent CCR2 antagonists
摘要:
We describe the synthesis and SAR of a new class of CCR2 antagonists based on a 2-mercaptoimidazole scaffold. The initial lead 1a was optimized to the 3,4-disubstituted analogues 1p-(S) and 1q-(S), which have IC50 values in the MCP-1 induced Ca-flux below 0.01 muM. (C) 2004 Elsevier Ltd. All rights reserved.
在重要的化学反应中具有高活性和选择性的纳米结构和可重复使用的 3d 金属催化剂是非常需要的。在这里,开发了一种钴催化剂,用于通过还原胺化反应合成伯胺,使用氢气作为还原剂,易处理的氨水溶解在水中,作为氮源。催化剂在非常温和的条件下运行(1.5 mol% 催化剂负载,50 °C 和 10 bar H 2压力)并优于市售的贵金属催化剂(Pd、Pt、Ru、Rh、Ir)。观察到广泛的范围和非常好的官能团耐受性。高活性的关键似乎是使用的载体:一种 N 掺杂的无定形碳材料,具有小的和乱层无序的石墨域,它是微孔的,具有双峰尺寸分布,并且在孔中具有基本的 NH 官能团。

A highly efficient and sustainable catalytic Staudingerreduction for the conversion of organic azides to amines in excellent yields has been developed. The reaction displays excellent functional group tolerance to functionalities that are otherwise prone to reduction, such as sulfones, esters, amides, ketones, nitriles, alkenes, and benzyl ethers. The green nature of the reaction is exemplified by
One-pot five-component reactions of oxathiazolidine-S-oxides with mesitylmagnesiumbromide, lithium bis(trimethylsilyl)amide, aldehydes and Grignard reagents afford chiral nonracemic amines or sulfinamides in good yields and high stereoselectivities.
