摘要

Abstract Wittig and Wittig-Horner reactions with α-phenylselenoaldehydes lead to allylic selenides. The corresponding selenoxides undergo 2, 3-sigmatropic rearrangement providing a route to α-hydroxy β, γ-ethylenic esters and ketones in good yields. In a same way, we prepare, also enals with an additionnal carbon.
