How Important Are Secondary Orbital Interactions in Favoring the Endo Mode in 1,3-Dipolar Cycloadditions of Nitrones?

Burdisso, Marina,Gandolfi, Remo,Gruenanger, Paolo,Rastelli, Augusto

, p. 3427 - 3429 (1990)

Experimental endo /exo selectivity data for the reaction of cyclic and open-chain nitrones with Z-disubstituted dipolarophiles as well as computational data cast serious doubt on the role of secondary overlaps as important endo orienting factors in nitrone cycloadditions.
