摘要
Abstract Tandem C−H‐arylation and C−H‐amidation of cis ‐cinnamyl hydroxamatesusing a single metal catalyst (and air as oxidant) leads to the formation of 3‐aryl‐2‐quinolone ring system in a regioselective manner. The corresponding trans‐isomer under identical conditions gives rise to 4‐aryl‐2‐quinolone derivative.The complementary regioselectivity observed during tandem C−H‐arylation C−H‐amidation of isomeric substrates is unusual and of potential application.
