Development of P-Spiro Chiral Aminophosphonium Salts as a New Class of Versatile Organic Molecular Catalyst

抄録

A series of P-spiro chiral tetraaminophosphonium salts have been designed and synthesized as a new class of organic molecular catalysts, and their inherent abilities to exert four different, synthetically relevant asymmetric catalyses have been brought out through the unique molecular design on a single core structure, N₄P⁺. Further, these catalyses have been applied to the development of various C-C, C-P, and C-N bond-forming reactions, in which the remarkably high catalytic performances and stereocontrolling abilities of the chiral tetraaminophosphonium salts have been successfully demonstrated.
