Two regioisomeric glucuronidemetabolites of dapagliflozin (BMS-512148) were synthesized and used to elucidate the structures of dapagliflozinmetabolites observed in human urine samples. The structures of the synthetic metabolites were assigned by heteronuclear multiple-bond correlation, ROESY, and total correlation spectroscopy experiments. Analogues of these metabolites containing carbon-13 as a
