Abstract
The 2,5-dimethyl-2'-hydroxy-9alpha- and-beta-propyl-6,7-benzomorphans were synthesized from 4-methyl-3-propylpyridine in five steps, in an overall yield of 14 and 5%, respectively. The required 4-methyl-3-propylpyridine was prepared in an overally yield of 34% by a four-step sequence. The benzomorphans were about as potent as, or more potent than, morphine in vivo.
