    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 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 present invention is directed to processes for the synthesis of morphinans. In particular, a process for coupling a carboxylic acid compound with an amine compound to form an amide product that can then be isolated or the crude amide product can be cyclized to form a 3,4-dihydroisoquinoline. In one embodiment, the carboxylic acid contains a phenol moiety protected with a labile protecting group. The protected phenol reduces reaction times, simplifies work-up of the product, and reduces the amount of cyclizing agent, POCl3 that is necessary to form the 3,4-dihydroisoquinoline.
