low residual metal content. The key steps used palladium on porous glass and a modifiedOppenaueroxidation, or Wilkinson’s catalyst. Dihydromorphone was prepared from morphine in high yield, excellent purity, and low residual metal content. The key steps used palladium on porous glass and a modifiedOppenaueroxidation, or Wilkinson’s catalyst.

Sulfate esters of morphine derivatives: Synthesis and characterization
of sulfation with pyridine-SO(3) complex and sulfuric acid/N,N'-dicyclohexylcarbodiimide. Complete (1)H- and (13)C-NMR assignments are given for each of the synthesized compounds based on one- and two-dimensional homo- and heteronuclear measurements. Comparative analysis of chiral properties by circulardichroism and opticalrotatorydispersion revealed characteristic differences in the spectra due

dihydroisomorphine-3-glucuronide were isolated from a cancer patient's urine and identified as metabolites of hydromorphone by comparison with synthetic standards using LC/MS/MS with gradient elution. 2. The relative urinary recovery of dihydroisomorphine-3-glucuronide was estimated to be 17-fold higher than previously reported. 3. Three new metabolites, including hydromorphone-3-sulphate, norhydromorphone and
