2,3-Wittig rearrangement
CHEMICAL REACTION
User:Mevans86/2,3-Wittig rearrangement; User:OrganicReactions/2,3-Wittig rearrangement
The [2,3]-Wittig rearrangement is the transformation of an allylic ether into a homoallylic alcohol via a concerted, pericyclic process. Because the reaction is concerted, it exhibits a high degree of stereocontrol, and can be employed early in a synthetic route to establish stereochemistry.
