Heterocyclic ketene aminals reacted with aryl isothiocyanates to give products of addition to the /?carbon. By oxidative cyclization o f these addition products by the action of bromine, isothiazole-fused heterocycles or benzothiazole-substituted heterocyclic ketene aminals were formed according to
