摘要

Enantioselective Diels-Alder reactions were conducted successfully using chiral magnesium complexes prepared from magnesium iodide and chiral hydroxysulfoxides derived from (R)- and (S)-methyl 1-naphthyl sulfoxide. Convenient methods for the preparation of these chiral sulfoxides have also been developed. Hydroxysulfoxide 6 (and its enantiomer 10) showed the highest enantioselectivity.
