a variety of novel peptide derivatives for chemical biology studies and potential pharmaceutical applications. The catalytic system tolerates a variety of functional groups including secondary amides, ester, nitrile, thiomethyl, and hydroxy groups. This convenient hydrosilylation reaction proceeds at ambient conditions and is operationally safe because no air‐sensitive reagents or highly reactive metal
描述了氨基酸衍生物和肽中叔酰胺键的有效还原。通过将可商购的铑前体和双(二苯基膦基)丙烷(dppp)配体与苯基硅烷一起用作还原剂,可以实现官能团的选择性。这种方法可以对生物学上感兴趣的肽进行特定的还原衍生,并可以直接访问各种新颖的肽衍生物,用于化学生物学研究和潜在的药物应用。催化系统可耐受各种官能团,包括仲酰胺,酯,腈,硫代甲基和羟基。这种便捷的氢化硅烷化反应可在环境条件下进行,并且操作安全,因为不需要空气敏感的试剂或高反应性的金属氢化物。
