Abstract

The reactions of N-(5,6-dihydro[1]benzothiepino[5,4-d]pyrimidin-4- yl)amidines or its amide oxime derivatives with hydroxylamine hydrochloride under basic condition gave abnormal cyclization products via a ring cleavage of pyrimidine component accompanied with a ring closure of [1,2,4]oxadiazole.
