6,7-BENZOMORPHAN DERIVATIVES HAVING ANALGESIC AND MORPHINE-ANTAGONISTIC PROPERTIES ARE OF THE FORMULA ##STR1## in which the substituents R are either lower alkyl groups or groups which, together with the carbon atom to which they are bonded, form a cycloaliphatic ring, and the substituents R.sub.1, R.sub.2 and R.sub. 3 may or may not be made and, if made, R.sub.1 represents either a hydrogen atom or an alkyl, haloalkyl, alkenyl, alkinyl, aralkyl, cycloalkenyl, cycloalkylalkyl, cycloalkenylalkyl or cycloalkylidine-alkyl group, R.sub. 2 is an alkyl, aryl, heteroaryl or aralkyl group, and R.sub. 3 is a hydrogen atom or an hydroxy, alkoxy, alkoxy-alkoxy or acyloxy group. Such 6,7-benzomorphans may be in the form of their optically active enantiomers and/or their therapeutically acceptable salts. There are also disclosed methods for producing such 6,7-benzomorphan derivatives, and intermediates useful in such production.
具有镇痛和吗啡拮抗性质的6,7-苯吗啡衍生物的结构式为##STR1##其中取代基R可以是较低的烷基基团或者与其结合的碳原子形成环状脂肪环的基团,取代基R.sub.1、R.sub.2和R.sub.3可以存在也可以不存在,如果存在,R.sub.1可以表示氢原子或者烷基、卤代烷基、烯基、炔基、芳基烷基、环烯基、环烷基烷基、环烯基烷基或环烷基亚烯基烷基,R.sub.2是烷基、芳基、杂环芳基或芳基烷基,R.sub.3是氢原子或羟基、烷氧基、烷氧基-烷氧基或酰氧基基团。这样的6,7-苯吗啡类化合物可以是其光学活性对映体和/或其治疗上可接受的盐的形式。还公开了生产这种6,7-苯吗啡衍生物的方法,以及在这种生产中有用的中间体。
