摘要：

The 1,3-dipolar cycloaddition of cyclic nitrones to several C-6 alpha,beta-unsaturated esters and lactones with different functionalities has been studied. All these olefins have shown high stereoselectivity, with a predominance of the exo or endo transition state for the cis or trans dipolarophiles, respectively. The antifacial approach is favoured in the reactions with gamma-substituted hexenolides and also with the substituted nitrone 21. (C) 1997 Elsevier Science Ltd.
