A simple protocol was introduced to prepare several enantiomerically pure heterocycles by using (-)-(1R, 2R, 3S, 4S)-3-aminonorbornene-2-carboxylic acid as a chiral auxiliary. The protocol is based on a domino ring-closure reaction, in which the relative configuration of the new asymmetric center is controlled by the stereochemistry of the amino acid, followed by a microwave-induced retro-Diels-Alder reaction.
