摘要：
The absolute configuration of alpha-hydroxy phosphonates was determined by NMR spectroscopy of the O-methyl mandelate ester derivatives. The O-methyl mandelate ester diastereoisomers are distinguishable by their H-1 and P-31 NMR spectra and the observed chemical shifts allow assignment of the absolute configuration of the phosphonate C-1. The crystal structure of (1R) dimethyl 1-[(2'R)-2'-methoxy-2'-phenylacetoxy]-3-phenyl-2E-propenyl phosphonate was determined by X-ray diffraction. The enatiomers were separable by HPLC on a chiral stationery phase and therefore the enantiomeric purity of the hydroxy phosphonates could accurately be determined.
