ABSTRACT:
Phosphinamides are prepared by the action of an organic halide on an oxazaphospholidine. Depending upon the configuration desired for the stereoisomer to be obtained, an oxazaphospholidine is utilized which has been derived from a (+) or (-) optically-active amino-alcohol. These phosphinamides are useful for the preparation of phosphinates, in particular optically-active phosphinates of known absolute configuration; for this, the phosphinamide is subjected to alcoholysis.
