摘要：
A new synthesis of homochiral vinyl phosphonates starting from 1-alkynes is described. The title compounds were obtained in good yields by the reaction of chiral 2-chloro-1,3,2-oxazaphospholidin-2-one (1) with the ''ate''-complexes of vinyl alanes. The latter were prepared by zirconocene dichloride catalyzed hydroalumination of 1-alkynes with diisobutyl aluminum hydride (DIBAH).
