We synthesized the glucuronides of MS-209 to identify the two main unknown
metabolites in human urine. Reaction of MS-209 and glucuronyl trichloroacet
imidate gave two beta-isomers, which were each glucuronate of (R)- and (S)-
MS-209. These spectrum data were identical with the metabolites. (C) 1999 E
