Transition-Metal-Free N9-Amidoalkylation of Purines with N,N-Dialkylamides
摘要:
A novel method for the selective N9-amidoalkylation of purines using N,N-dialkylamides as alkylation reagents via activation of sp(3) C-H bond adjacent to an amide nitrogen atom has been developed in the presence of KI and tert-butyl hydroperoxide (TBHP). This method was simple to operate and provided series of purine derivatives in moderate to excellent yield.

An oxidative coupling reaction between purines and aromatic N-heterocycles was developed to synthesize a series of N-heteroaryl purine derivatives using Selectfluor as an oxidant at room temperature. This process uses a commercial oxidant, uses no base, metal, or other additives, is simple to carry out, and has a broad range of substrates.
