Salutaridine and its derivatives as thebaine-equivalents in the synthesis of aporphines [PDF]
Open Chemistry, 2013 Here we report on the transformation of tetracyclic morphinan salutaridine (1) into 2,3,10,11-tetrasubstituted (R)-aporphines. This method serves as another chemical proof of the previously verified biosynthetic connection with pentacyclic ...
