A copper-catalyzed aerobic oxidative cross-dehydrogenative coupling (CDC) of amines with α-carbonyl aldehydes leads to various α-ketoamides compounds. Many types of amines are tolerant in this transformation. Wide substrate scope, and the use of air as oxidant and initiator make this transformation highly efficient and practical.
