标 题 :Total synthesis of northebaine, normophine, noroxymorphone enantiomers and derivatives via N-Nor intermediates
发明人：RICE KENNER CRALLE; NEWMAN AMY HAUCK
权利人:US HEALTH
摘要:The invention involves a method of making key intermediates useful in the synthesis of many opiate narcotics and antagonists and agonists; and the non-opiate enantiomers thereof which have potent antitussive properties. The synthesis starts from either the natural or unnatural enantiomer of nordihydrocodeinone and produces 8, 14-dihydronorthebaine, the diketal of 7-bromonordihydrocodeinone, northebaine, norcodeinone diketal and 14-hydroxynorcodeinone intermediates without the necessity of leaving the N-nor structure. The syntheses have fewer steps than previous methods, and also have high yields.

摘要:A solid phase synthetic method for making substituted 1,5-benzodiazepine-2-one or 1,5-benzothiazepine-2-one. The method is useful for synthesis of large numbers of compounds through automated parallel synthesis or combinatorial library generation and is thus important to rapid discovery or new therapeutic agents containing the base structure of 1,5-benzodiazepine-2-one or 1,5-benzothiazepine-2-one.
