ABSTRACT:
Novel opiate intermediate compositions and methods of synthesis that include changing the substitution pattern on the aromatic ring of the pre-Grewe intermediate are provided. The intermediates are morphinane derivatives of formula (10), wherein X is a F or Cl and R is selected from the group consisting of an H, alkyl, aryl, acyl, formyl, COR″, CONHR″, COOR, Bn(benzyl), alkyl(methyl), and sulfonamide SO2CH2COPh.
