摘要

A metal-free process for the C-3 alkylation of imidazopyridines has been developed. Various alkylation products including alkyl ester-, cyano-, ketone- and amide-substituted imidazopyridines were prepared in good yields. With this method, a highly efficient and concise formal synthesis of alpidem ( A ) and zolpidem ( B ) has been completed.
