The acid chlorides of (S)-Naproxen(R) and (S)-lbuprofen(R) are shown to be convenient chiral derivatizing agents for determination of the enantiomeric purity of diethyl 1-hydroxy- and 2-hydroxyalkylphosphonates as well as their aminoalkylphosphonate analogues by means of P-31 NMR spectroscopy. Correlation between the phosphorus chemical shift and the absolute configuration of the 1-hydroxyalkylphosphonate is also discussed. (C) 2002 Elsevier Science Ltd. All rights reserved.
