Orally active nonaddicting analgesics |
| abstract |
Stereoisomerically pure forms of normorphine analogs which have superior analgesic and nonaddicting qualities. In addition, a method of separating diastereomeric forms of N-sec-alkyl-substituted analogs utilizes the hydrocarbyl (1-8C) diesters of the normorphine derivatives. A new method for preparing the N-methylalkylmethyl derivatives of normorphine and norcodeine and their conventional analogs is also disclosed. This method employs the corresponding methyl alkyl ketones and a reducing agent. |
