An efficient and straightforward procedure toward the synthesis of amides-substituted 2H-benzopyrans has been explored through palladium-catalyzed one-pot aminocarbonylation reaction. By using nitro compounds as attractive nitrogen sources, with Mo(CO)6 as both CO source and reductant, a variety of amides-containing 2H-benzopyrans were obtained in moderate to high yields with good functional group tolerance. This protocol has advantages including atom-economy, no manipulation of toxic CO gas, and broad substrate scope.
