The Delta(3)-imidazoline 3-oxides 1 undergo diastereoselective cycloaddition with dimethyl acetylenedicarboxylate 2 to give 3a,4,5,6-tetrahydroimidazo[1,5-b]isoxazoles 3. Thermal and base induced ring-opening reactions of compounds 3 were demonstrated. (C) 2000 Elsevier Science Ltd. All rights reserved.
