title: Synthesis and analgetic activity of 1,2,3,4,5,6-hexahydro-1,6-methano-3-benzozocines.
abstract: 1,2,3,4,5,6-Hexahydro-1,6-methano-3-benzazocine (1) has been synthesized via a four-step sequence from benzo-norbornadiene. This compound and its N-methyl derivative are more active than codeine in the mouse hot-plate antinociceptive assay and will not suppor morphine dependence in Rhesus monkeys.
