1,3‐dipolar cycloaddition of methyl 3‐(1‐imidazolyl)acrylate and related compounds

Abstract

Abstract The 1,3‐dipolar cycloaddition reaction of 1‐vinylimidazole and β‐(1‐imidazolyl)‐α,β‐unsaturated carboxylic esters with N.α ‐diphenylnitrone and acetonitrile oxide was carried out and compared with those of β‐pyrrolidinyl‐ and β‐phenyl‐α,β‐unsaturated carboxylic esters. The imidazolyl moiety bonded to olefinic double bond was suggested to have properties intermediate to pyrrolidinyl and phenyl groups.
