A novel one-pot multicatalytic route for the synthesis of 3-methyleneindolin-2-ones has been developed involving sequential copper-catalyzed amination and palladium-catalyzed C–H functionalization processes. In the presence of CuI and Pd(OAc)2, a variety of propiolamides underwent the reaction with iodides to afford the corresponding 3-methyleneindolin-2-ones in moderate yields.

catalyzed single-step, stereoselective domino synthesis of symmetrically and unsymmetrically all-carbon tetrasubstituted olefin containing oxindoles from readily accessible anilides has been developed. The Pd-BNP catalyst showed a wide range of functional group tolerance that enabled building a library of heteroaromatics. This reusable Pd catalyst reflected its utility in the synthesis of biologically important
