Novel 3-amino-4-oxo-2,3,4,5-tetrahydro-1,5-benzoxazepine derivatives of the formula ##STR1## [wherein R.sup.1 and R.sup.2 are independently hydrogen, halogen trifluoromethyl, lower alkyl or lower alkoxy, or both jointly form tri- or tetramethylene; R.sup.3 is hydrogen, optionally substituted lower alkyl or optionally substituted aralkyl; R.sup.4 is hydrogen, optionally substituted alkyl, optionally substituted aralkyl or optionally substituted cycloalkylalkyl; Y is a carboxyl group which may be esterified or amidated; m is 1 or 2] and salts thereof. These compounds and salts thereof exhibits inhibitory activity on angiotensin converting enzyme and so forth, and are of value as an agent for diagnosis, prevention and treatment of circulatory diseases (e.g. hypertension, cardiopathy, cerebral apoploxy).
化合物和盐的新颖3-氨基-4-氧代-2,3,4,5-四氢-1,5-苯并噁唑衍生物的公式为##STR1##[其中R.sup.1和R.sup.2独立地为氢,卤素三氟甲基,低级烷基或低级烷氧基,或共同形成三亚甲基或四亚甲基; R.sup.3为氢,可选择取代的低级烷基或可选择取代的芳基烷基; R.sup.4为氢,可选择取代的烷基,可选择取代的芳基烷基或可选择取代的环烷基烷基; Y为可酯化或酰胺化的羧基; m为1或2]。这些化合物及其盐表现出对血管紧张素转换酶等的抑制活性,并具有作为循环疾病(如高血压,心脏病,脑卒中)的诊断,预防和治疗剂的价值。
