    摘要: The present disclosure generally relates to a process for converting a fused, tricyclic compound to a fused, tetracyclic compound that includes a furan ring therein. More particularly, the present disclosure related to a process for preparing a hydrocodone compound, or a compound structurally related thereto, and in particular (+)-hydrocodone, by subjecting a structurally corresponding sinomenine starting compound to a super acid-assisted furan ring closure reaction.

    摘要: The present invention provides processes for the preparation of saturated ketone morphinan compounds from a morphinan comprising an allyl alcohol ring moiety, wherein the final product has a low metal content. In particular, the invention provides processes that utilize isomerization reactions catalyzed by transition metal catalysts and the subsequent removal of the transition metal using metal scavengers.
