Pd/C and RuCl2(PPh3)3/DPEphos effectively catalyzed the alkylation of indole with alcohols to give 3‐substituted indoles selectively. Various types of substrates were examined and were found to give the corresponding 3‐substituted indoles in up to 99 % yield. Under different reaction conditions, RuCl2(PPh3)3/DPEphos catalyzed the selective formation of bis(3‐indolyl)phenylmethane derivatives.
Achieving divergence in CH alkylation of substrates using feedstock chemicals is an attractive paradigm to enable the production of diverse products from the same starting materials. Herein, we report manganese-catalyzed CH alkylation of indole/indolines with alcohols, where product selectivity is achieved through catalyst control. By use of a molecularly defined PNP–Mn(I) complex, tandem double dehydrogenative
使用原料化学品实现底物 CH 烷基化的差异是一个有吸引力的范例,可以从相同的起始材料生产不同的产品。在此,我们报道了锰催化的吲哚/二氢吲哚与醇的CH烷基化反应,其中产物选择性是通过催化剂控制实现的。通过使用分子定义的 PNP-Mn( I ) 络合物,观察到吲哚的串联双脱氢 CH 烷基化。相比之下,NNN-Mn( II )基催化剂系统通过以下方式提供多种增值双(吲哚基)甲烷(BIM):中断的借氢策略。目前的策略已成功应用于多种生命科学分子(vibrindole A、涡轮霉素 B 生物碱、抗白血病和抗癌药物)和天然产物(禾本科胺、敌蝶呤等)的可持续、可扩展合成。

Disclosed is a compound of formula (I), where R1 to R4 are as defined herein, and a method for treating a viral infection in a subject in need thereof by administering with the compound. Also provided is a method for screening a compound capable of inhibiting activities of a coronavirus in a host cell, including identifying a compound that modulates a non-native protein-protein interaction in coronaviral nucleocapsid (N) proteins.
Identification of a Novel PPAR-γ Agonist through a Scaffold Tuning Approach
fatty liver disease. Recently, they have been highlighted as attractive targets for the treatment of cardiovascular diseases and chronic myeloid leukemia. The PPAR agonist structure is consists of a polar head, a hydrophobic tail, and a linker. Each part interacts with PPARs through hydrogen bonds or hydrophobic interactions to stabilize target protein conformation, thus increasing its activity. Acidic

interesting class of heterocyclic compounds widely used in organic synthesis and medicinal chemistry. Key for this synthesis is the use of specific cobalt-nanoparticles supported on N-doped carbon, which were conveniently prepared by the pyrolysis of a templated material generated in situ by mixing cobalt-nitrate, zinc-nitrate, 2,6-diaminopyridine, and colloidal silica, and subsequent removal of silica
