  摘要：

  3,6-Dimethoxy-7 beta, 17-dimethyl-4-hydroxy-5,6,8,14-tetradehydromorphinan (2) was converted to the 4-deoxy compound 4 and hydrolyzed to a mixture of the B/C-cis (C series) and B/C-trans (T series) isomers of 7,8-didehydromorphinan-6-one, 5. Hydrogenation of the separated isomers gave 7-methyl-6-oxo derivatives 6a. 7,8-Dimethyl-(6b) or 7-methyl-8-ethylmorphinan-6-one (6c) was prepared by reaction of 5 with lithium organocuprates. The analgesic N-methyl compounds 6 were converted to 17-(cyclopropylmethyl) or 17-(cyclobutylmethyl) derivatives 10--13. Some of these compounds had mixed profiles of narcotic agonist-antagonist effects. Studies with drug-dependent monkeys indicated that several of these compounds with an analgesic-antagonist ratio of less than 0.4 substitute for morphine.
