The synthesis of three new vinylketene acetals, each bearing a heteroatom substituent at C3 of the diene unit, and their reactions with representative dienophiles in Diels-Alder reactions are presented. All the dienes react well at room temperature, indicating substantial activation of the cycloaddition event. The stereochemistry of the major Diels-Alder product of a 3-SPh-substituted vinylketene acetal
