    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 invention provides processes for the preparation of morphinans having a tertiary amine. In particular, the present invention provides processes for the formation of tertiary amine alkaloids by direct N-alkylation of secondary amine alkaloids, the processes co-mediated by an alkylating agent and a protic solvent or a mixture of a protic solvent and an aprotic solvent.
