AbstractThe efficient construction of CN double bonds has been achieved by the Ir‐catalyzed intramolecular acceptorless dehydrogenative cross‐coupling of tertiary amines and amides. An iridium/2‐hydroxypyridine complex was identified as the highly efficient catalyst. A number of quinazolinone derivatives was prepared in excellent yields. An iridium‐mediated CH activation mechanism is proposed. This finding provides an unprecedented strategy for the direct imidation of sp3 CH bonds.magnified image
