Chiral 2-alkenyloxazolines and 2-alkenylthiazolines react with isocyanates and ketenes to give formal hetero-Diels-Alder adducts with complete diastereocontrol. In each case an electron-rich double bond in the adduct is prone to a second addition of the heterocumulene. In the case of the oxazoline adducts the second addition is faster than the first, while with thiazolines the second addition is slower
