Abstract
The first preparation of optically active α, β-unsaturated phosphonyl compounds from chiral phenylsulfenylmethanephosphonates 1 and 2 has been described. The optically active α, β-unsaturated sulfoxides have also been prepared by the Emmons-Horner reaction of phenylsulfinylmethanephosphonamidate 4 with several aldehydes.
