Construction of a Chiral Quaternary Carbon Center via 1,2-Acyl Migration of an Optically Active α,β-Epoxy Ketone
The construction of a chiral building block with a quaternary carbon center is described, based on the Lewis acid-catalyzedacylmigration of α,β-epoxy ketone with alkyl and alkenyl substituents.
