INTRAMOLECULAR N-ALKENYLNITRONE-ADDITIONS. REGIO- AND STEREOCHEMISTRY

Oppolzer, W.,Siles, S.,Snowden, R. L.,Bakker, B. H.,Petrzilka, M.

, p. 3497 - 3509 (2007/10/02)

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.
