Synthesis of urine drug metabolites: glucuronic acid glycosides of phenol intermediates

The investigation of drug metabolism requires substantial amount of metabolites. Isolation from urine is tedious, therefore, the material obtained by synthesis is preferred. Substantial amounts of three tentative drug metabolites, phenolic glucuronides, have been prepared using easily available glycosyl donors. The final products [3(2-N-methyl-N-isopropylaminoethoxy)phenyl] β-d-glucopyranosiduronic acid, 4-amino-3,5-dimethylphenyl β-d-glucopyranosiduronic acid and [2(S)-propanoyl-6-O-naphthyl] β-d-glucopyranuronic acid are useful as, for example, reference material in metabolite investigations.
