Selective Synthesis of Cyclic Compounds
under Transition Metal Catalysis

Dr. Shintani designed and utilized new organic reagents for palladium-catalyzed stereoselective intermolecular addition/cyclization reactions, highlighting efficient generation and use of zwitterionic π-allylpalladium intermediates bearing pendant nucleophilic sites. This method allows for the preparation of a diverse array of carbo- and heterocycles that are difficult to synthesize with existing methods, and mechanistic studies on these catalytic reactions have also been successfully carried out.
