Stereoselective [2,3]-Wittig and tandem [2,3]-Wittig-anionic oxy-Cope rearrangements of bis-allylic ethers: Effect of substituents

Article abstract of DOI:10.1016/S0040-4039(97)01473-1

Acyclic bis-allylic ethers undergo, syn or anti stereoselective [2,3]-Wittig rearrangement to give hemoallylic alcohols depending on the substituents, and E-selective tandem [2,3]-Wittig-anionic oxy-Cope rearrangement to give δ,ε-unsaturated aldehydes.
