Versatile ruthenium(II) complexes allow for site‐selectiveCH oxygenations with weakly‐coordinating aldehydes. The challenging CH functionalizations proceed with high chemoselectivity by rate‐determining CH metalation. The new method features an ample substrate scope, which sets the stage for the step‐economical preparation of various bioactive heterocycles.

alpha (PPARα) in retinal biology is clarifying, and evidence demonstrates that novel PPARα agonists hold promising therapeutic utility for diseases like diabetic retinopathy and age-related macular degeneration. Herein, we disclose the design and initial structure–activityrelationships for a new biarylaniline PPARα agonistic chemotype. Notably, this series exhibits subtype selectivity for PPARα over
过氧化物酶体增殖物激活受体 α (PPARα) 在视网膜生物学中的作用正在逐渐阐明,并且有证据表明新型 PPARα 激动剂对于糖尿病视网膜病变和年龄相关性黄斑变性等疾病具有良好的治疗作用。在此,我们公开了一种新的联芳基苯胺 PPARα 激动化学型的设计和初始构效关系。值得注意的是,与其他亚型相比,该系列对 PPARα 表现出亚型选择性,这种现象被认为是由于独特的苯甲酸头基所致。该联苯苯胺系列对 B 环官能化敏感,但允许等排取代,并提供 C 环延伸的机会。在该系列中, 3g 、 6j和6d被确定为 <90 id=3> 体外和体内模型的先导化合物。
