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.
