salt-based catalyst system utilizing the hydrogen surrogacy of sodiumborohydride for selective hydrogenation of a broad range of nitro substrates into the corresponding amine under habitancy of water or methanol like green solvents have been described. Moreover, this catalytic system can also activate various functional groups for hydride reduction within prompted time, with low catalyst-loading, without
摘要 第一个温和、原位、单锅、高收率、筛选良好的铜 (II) 盐基催化剂体系,利用硼氢化钠的氢替代作用,在存在于已经描述了水或甲醇之类的绿色溶剂。此外,该催化体系还可以在短时间内活化各种官能团进行氢化物还原,催化剂负载量低,无需高压或分子氢供应。值得注意的是,该系统探索了替代昂贵的传统加氢方法的巨大潜力,从而在有机合成领域提供了一种更绿色、更简单的加氢策略。

regioselective synthesis of oxazolines in high yields. The mild photosensitized manifold leverages the intermolecular formation of oxazolines with a wide functional group tolerance on both benzoyl azides and alkenes partners. Mechanistic investigations suggest the sensitization of the azide moiety as the key activation step.
Design, synthesis, biological evaluation and molecular docking study of novel urea-based benzamide derivatives as potent poly(ADP-ribose) polymerase-1 (PARP-1) inhibitors
Herein, a series of novel urea-based benzamide derivatives were designed and synthesized based on the structure-based drug design strategy. The anticancer activities against five human cancer cell lines including HCT116, MDA-MB-231, HeLa, A579 and A375 were evaluated and the preliminary structure-activity relationships were summarized. Among them, compounds 23f and 27f exhibited potent antiproliferative
