Enantioselective organocatalytic inverse-electron-demand hetero-Diels-Alder reactions of in situ generated ortho-quinone methides with azlactones have been developed. This strategy could generate various chiral dihydrocoumarins bearing a quaternary amino acid moiety in high yields (up to 94%) and stereo-selectivities (up to 99 : 1 e.r., > 20 : 1 dr) in the presence of a chiral phosphoric acid catalyst. The useful transformation and mechanistic study of this process are also presented.
