Abstract

A chiral Lewis acid-catalyzed highly enantioselective [4 + 3] cycloaddition reaction of allenamide-derived nitrogen-stabilized chiral oxyallyl cations is described here. The use of bisoxazoline ligand and CuOTf2 provides high enantioselectivity, especially with [SbF6]- as the counteranion.
