| titleOfInvention | Process for preparing hydrocodone using a super acid |
| abstract | 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 sinomeπine starting compound to a super acid-assisted furan ring closure reaction. Formula I, II. Examples of super acids useful in the processes described herein include, but are not limited to, trifluoromethanesulfonic acid (CF |
