A direct highly diastereo- and enantioselective asymmetric vinylogous Mannich-type (AVM) reaction of aldimines with nonactivated natural α-angelica lactone has been successfully developed. It was demonstrated that the nonactivated natural α-angelica lactone is a useful vinylogous nucleophile to give the chiral

The first organocatalytic asymmetric assembly of Morita-Baylis-Hillman carbonates of isatins and α-angelica lactone has been studied, affording multifunctional products containing two valuable pharmacophores and vicinal quaternary chiral centers in high stereoselectivity (up to 92% ee, dr >95:5).
