Abstract:
The present invention provides processes for preparing normorphinans from N-substituted morphinans. In particular, the invention provides methods for removing the N-substituent from the N-substituted morphinan to from a normorphinan carbamate, and then removing the carbamate functionality from the normorphinan carbamate to form the normorphinan.
