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特性的6,7-苯并吗啡衍生物的化学式为##STR1##其中置换基R可以是较低的烷基或与其结合形成环脂族环的基团,而置换基R.sub.1,R.sub.2和R.sub.3可以制备或不制备,如果制备,R.sub.1代表氢原子或烷基,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甲基基团,R.sub.2是烷基,芳基,杂芳基或芳基烷基基团,而R.sub.3是氢原子或羟基,烷氧基,烷氧基烷氧基或酰氧基。这些6,7-苯并吗啡衍生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。还公开了制备这些6,7-苯并吗啡衍生物的方法和在这种制备中有用的中间体。
