Catalytic Enantioselective Ring-Opening and Ring-Closing Reactions of 3-Isothiocyanato Oxindoles and N-(2-Picolinoyl)aziridines.

Abstract

3-Isothiocyanato oxindoles have been successfully applied to an asymmetric formal [3 + 3] cycloaddition reaction with aziridines for the first time. The reaction was efficiently mediated by an in situ generated magnesium catalyst employing (R)-3,3'-fluorous-BINOL as a simple chiral ligand. Serials of polycyclic frameworks could be obtained after a ring… (More)
