An N,N'-dioxide/zinc bis(trifluoromethylsulfonyl)imide complex has been developed as an efficient catalyst for the highly enantioselective Diels-Alder reaction of cyclopentadiene with alkynones. Various 2-acyl substituted norbornadiene derivatives were obtained in moderate to high yields (up to 99%) with good enantiomeric excesses (up to 95%).
