Water-Controlled Regioselectivity of Pd-Catalyzed Domino Reaction Involving a C-H Activation Process: Rapid Synthesis of Diverse Carbo- and Heterocyclic Skeletons

A palladium-catalyzed domino reaction involving a C-H activation process to synthesize diverse carbo- and heterocyclic skeletons was developed. H2O (as cosolvent) is used to control the regioselectivity.
