Abstract

It has been shown that the reaction of epichlorhydrin with 3-hydroxybenzimidazo[2,1-b]thiazanium salts leads to recyclization of the thiazanium ring with the formation of substituted 1-(2,3-epithiopropyl)benzimidazol-2-ones in high yield. The proposed method enables the introduction of functional groups unstable in alkaline medium into the structure of thiirane derivatives.
