10,11-Epoxy-3-methyl-1,2,3,4-tetrahydro-4a,10b-propanobenzo[f]isoquinolin-12-ones: A Novel Type of Opioid Analgesics — Synthetic Approach and Structure Elucidation
摘要:
The title compounds were obtained by nucleophilic cyclopropane ring opening and intramolecular Hofmann reactions, starting from 7,14-cyclo-dihydrocodeinone (1). An X-ray analysis of 10,11-epoxy-9-methoxy-3-methyl-1,2,3,4-tetrahydro-4a,10b-propanobenzo[f]isoquinolin-12-one dimethyl acetal (3) was performed as basis of molecular modeling studies.
