1,3-dipolar cycloadditions of cyclic nitrones to γ-bromo γ,β- unsaturated esters and lactones

Abstract:

The 1,3-dipolar cycloaddition of cyclic nitrones to several γ-bromo α,β-unsaturated esters and lactones has been studied. All the reactions have shown high stereoselectivity, with a predominance of the endo or exo transition state for the trans or cis dipolarophiles, respectively.
