The chiral c,d-olefin (2S)-2-(tert-butyl)-5-methylene-1,3, dioxolan-4-one(1) is an effective dienophile in normal and inverse Diels-Alder reactions. In the thermal reaction of 1 with ethyl 4-oxo-2-butenoate (2) only two of the four possible diastereoisomers are formed. Accordingly the reaction of 1 with acrolein (7) yields only one of the two possible Diels-Alder adducts.
