摘要:
The present invention provides processes for the demethylation of an N-methyl morphinan comprising a ketone functional group. In particular, the invention provides methods for the protection of the ketone functional group such that impurities are not generated during the demethylation of the N-methyl morphinan.
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.
