The present application describes processes for the synthesis of morphinane and morphinone compounds, useful as pharmaceutical agents. Also included are novel intermediates useful in the preparation of these compounds. The process comprises quaternization of oripavine to provide a mixture of the R- and S-isomeric (at the nitrogen) quaternary salts. The R-isomer is readily isolated and converted to various N-(R)-morphinane and N-(S)-morphinone compounds. The R-isomer, S-isomer or a mixture of R- and S-isomers may be demethylated and converted to various morphinane and morphinone compounds.
