Abstract
Enantiomeric (S, S)- and (R,R)-bis(1-phenylethyl)diamidomethylphosphon ates, the phosphorus atom being prochiral, have been synthesized, star ting from the methanephosphonic acid dichloride and corresponding chir al amines. The splitting observed in the P-31-NMR spectra of their non racemic mixtures may be accounted for the self-discrimination of chira l species. This effect can be very useful for enantiomeric analysis of amines based on coupling reactions with methanephosphonic acid dichlo ride. (C) 1994 Wiley-Liss, Inc.
