α,β-Unsaturated thioesters and selenoesters serve as dienophiles in Diels-Alder reactions with a variety of 1,3-dienes. Good levels of regioselectivity are obtained with unsymmetrical dienes when Lewis acid promoters are used. Thioesters and selenoesters are more reactive than the corresponding methyl esters based on competition experiments with cyclopentadiene.
