Abstract

The use of potassium tert-butoxide enables transamidation of primary and tertiary amides with a range of aryl, heteroaryl, and aliphatic amines at room temperature under transition-metal-free conditions to provide secondary amides in high yields. Moreover, the reaction of cyclopropyl amine with tertiary amides delivers enamides.
