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:The invention relates to commercially viable process for the synthesis of key intermediates for the preparation of statins, in particular Rosuvastatin and Pitavastatin or respective pharmaceutically acceptable salts thereof. A new simple and short synthetic route for key intermediates is presented which benefits from the use of cheap and readily available starting materials, by which the conventionally most frequently used DIBAL-H as reducing agent can be avoided.

摘要:Novel phosphonate compounds are described. The compounds have activity as neuraminidase inhibitors against wild-type and H274Y mutant of H1N1 and H5N1 viruses. The present disclosure also provides an enantioselective synthetic route to known neuraminidase inhibitors oseltamivir and the anti-flu drug Tamiflu®, as well as novel phosphonate compounds, via D-xylose. Another efficient and flexible synthesis of Tamiflu and the highly potent neuraminidase inhibitor Tamiphosphor was also achieved in 11 steps and >20% overall yields from the readily available fermentation product (1S-cis)-3-bromo-3,5 -cyclohexadiene-1,2-diol. Most of the reaction intermediates were obtained as crystals without tedious purification procedures. The key transformations include an initial regio- and stereoselective bromoamidation of a bromoarene cis-dihydrodiol, as well as the final palladium-catalyzed carbonylation and phosphonylation.

摘要:Families of antagonist-agonists and opiate narcotics are produced from norhydrocodeinone. In a preferred embodiment, norhydrocodeinone is refluxed with sulfosalicyclic dimethylketal and delta-6-enol ether derivatives and is then converted entirely to the ether by the addition of dry tetrahydrofuran simultaneously with the removal of the thus produced ether. The ether is then reacted with methanesulfonic acid and N-bromoacetamide to form the hydrobromide salt of the 7-bromodimethylketal derivative. From this derivative, a variety of products can be derived, including the novel further intermediate 14 hydroxynorcodeinone. The present invention enables derivation using a starting material which, unlike the starting materials of prior art processes, is available in the natural (-) or synthetic (+) form. Thus, the method of the present invention provides the only known route for the synthesis of (+) forms of various derivatives and intermediates, such as (+)-7-bromo-dimethylketal nordihydrocodeinone.
