Notes:
The chromatographic resolution of the four stereoisomers of carboxyibuprofen, a major metabolite of ibuprofen in man, was achieved using a Chiralpak AD chiral stationary phase (CSP) (J.T. Baker, Milton, Keynes, UK). The elution order of the stereoisomers was determined to be 2′S,2R; 2′R,2R; 2′R,2S; 2′S,2S by a combination of stereoselective synthesis of diastereoisomeric mixtures and analysis of the two diastereoisomers isolated from human urine following the administration of (S)-ibuprofen. The individual stereoisomers were isolated by semipreparative chiral phase chromatography and characterized by circular dichroism spectroscopy. Chirality 9:75-87, 1997. © 1997 Wiley-Liss, Inc.
