Cyclization of N-allylthiourea derivatives by the action ofα-chloronitrosoalkanes

Chemistry of Heterocyclic Compounds Aims and scope

Abstract

A convenient method is proposed for obtaining difficultly available derivatives of 2-amino-5-chloromethyl-2-thiazoline by the cyclization of N-allythioureas under the action ofα-chloronitrosoalkanes. It is assumed that the reaction proceeds as a halogenophilic process leading to the intermediate formamidinesulfenyl chloride which is rapidly and selectively cyclized with the formation of 2-amino-2-thiazoline derivatives.
