Abstract

An efficient NHC-catalyzed domino oxidation/oxa-Michael addition reaction of 2- alkenylbenzaldehydes has been developed to afford 3-substituted phthalides bearing a C3- stereogenic center with a broad substrate scope and wide functional group tolerance. The preliminary results of the asymmetric process have been provided as well.
