Enantiopure sulfinylnaphthoquinone (+)-1 reacted with racemic acyclic dienes 2a-f bearing a stereogenic allylic center, through a tandem cycloaddition/pyrolytic sulfenic acid elimination, to afford enantio-enriched compounds 4a-f and 5a-f with good like:unlike selectivities (ca. 75:25) and good enantiomeric excesses (68-82%), arising from the partial kinetic resolution of the racemic dienes.
