Catalyst-Free Regioselective C-3 Thiocyanation of Imidazopyridines
摘要:
A direct and straightforward approach for highly regioselective thiocyanation of imidazoheterocydes through sp(2) C-H functionalization has been realized at room temperature. Various C-3 thiocyanated imidazopyridines are formed in moderate to good yield. The present method exhibits a mild and selective access to a variety of imidazopyridine derivatives of pharmacological interest.
