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