摘要

Efficient intramolecular cycloadditions of N-3-alkenyl-and N-4-alkenylnitrones proceed with opposite regioselection which is modified by dipolarophile-substituent effects. Polycyclic isoxazolidines are obtained in a highly stereocontrolled fashion, consistent with an endo- addition of the Z-nitrones.
