摘要:
2-Trimethylsiloxyfuran underwent a vinylogous Mannich-type reaction with aldimines under the action of a new chiral phosphoric acid, bearing iodine on the 6,6'-positions of the binaphthyl group, as a chiral Bronsted acid to give gamma-butenolide derivatives bearing an amino functionality with high diastereo- and enantioselectivity.
