摘要:

AbstractEnantiomeric (S,S)‐ and (R,R)‐bis(1‐phenylethyl)diamidomethylphosphonates, the phosphorus atom being prochiral, have been synthesized, starting from the methanephosphonic acid dichloride and corresponding chiral amines. The splitting observed in the31P‐NMR spectra of their nonracemic mixtures may be accounted for the self‐discrimination of chiral species. This effect can be very useful for enantiomeric analysis of amines based on coupling reactions with methanephosphonic acid dichloride. © 1994 Wiley
