摘要:
The present invention provides an efficient process for the preparation of hexahydroisoquinolines from dihydroisoquinolines. In particular, the invention provides a good yielding, one-pot process for the synthesis of hexahydroisoquinolines.
摘要:
The invention provides a process for the conversion of opioid derivatives into normorphinan compounds useful for making “nal” compound analgesics and antagonists. In particular, the process may be used for the production of pure normorphinan salts from crude opioid substrates.
摘要:
The present invention provides a synthetic process for the N-demethylation of N-methyl morphinans. In particular, the invention provides improved synthetic methods for the preparation of N-demethylated morphinan compounds that may be employed as starting materials, for example, commonly available N-methyl opiates such as oripavine and thebaine, and C(3)-protected hydroxy derivatives of oripavine.
摘要:
The present invention provides (+)-morphinanium quaternary salts. The invention also provides processes for producing (+)-morphinanium quaternary salts from tertiary N-substituted (+)-morphinan compounds.
摘要:
The invention generally provides processes and intermediate compounds useful for the production of sinomenine derivatives. In particular, the process may encompass synthetic routes for the production of (+)-sinomenine derivatives and their intermediates.
摘要:
The invention generally provides processes for the production of buprenophine and derivatives of buprenorphine. In particular, the process may encompass synthetic routes for the production of buprenorphine or derivatives of buprenorphine from norhydromorphone or derivatives of norhydromorphone.
