Synthesis of Alkyl-Substituted Pyridines by Directed Pd(II)-Catalyzed C–H Activation of Alkanoic Amides
摘要:
A general alkylation protocol for substituted iodopyridines was developed (32 examples, 44-97% yield). The reaction is based on the Pd(II)-catalyzed C-H activation of 8-aminoquinoline-derived alkanoic amides and it employs a catalyst cocktail of Pd(OAc)(2) (10 mol%), NaI (30 mol%), and (BuO)(2)POOH (20 mol%), with Ag2CO3 as base.
