Abstract

The site-selective functionalization of cyclic amides provides an attractive protocol for the synthesis of valuable molecules. We report herein an electrochemical desaturation and β-thiocyanation of cyclic amides under external oxidant-free conditions. This method exhibits broad functional group tolerance, excellent selectivity, mild reaction conditions and can be applied for late-stage functionalization of bioactive molecules. Mechanistic studies indicate that an enamide intermediate might be involved.
