Levo-rotary 3-phenoxy N-substituted morphinans and derivatives thereof useful as analgesics and/or narcotic antagonists and their preparation form (-)-3-hydroxy-N-lower alkyl morphinan including intermediates in this preparation.
A new and distinct cultivar of
Hydrangea
plant named ‘H217905’, characterized by its upright and rounded plant habit; vigorous growth habit and rapid growth rate; freely branching habit with strong, thick and sturdy stems; early, freely and uniformly flowering habit; mophead-type inflorescences with numerous intense red purple-colored sterile flowers; and good postproduction longevity.
The preparation of 3-phenoxy N-substituted morphinans, useful as analgesics from 1-(p-hydroxybenzyl)-1,2,3,4,5,6,7,8-octahydroisoquinoline or cyclohexen-(1)-yl-ethylamine and p-phenoxyphenylacetic acid is described.
A series of novel O-aryl-N-methylmorphinans (7-19) were synthesized by the Ullmann reaction from levorphanol (4) in our search for a synthetic codeine (2) substitute with reduced addition liability. The compounds were evaluated for antinociceptive potency and receptor binding affinity. Among these compounds, (-)-3-phenoxy-N-methylmorphinan (7) is an orally active analgesic comparable in potency to codeine (2), which exhibits decreased physical dependence liability and longer duration of action.
