Mesyloxy-group migration as the stereoselective preparation method of various functionalized olefins and its reaction mechanism

It was demonstrated that mesylation of appropriate γ,γ-difluorinated allylic alcohols under usual conditions furnished the corresponding α,γ-difluorinated allylic mesylates, possibly by way of 1,3-mesyloxy-group migration after formation of the expected "normal" intermediates, γ,γ-difluorinated allylic mesylates. This rearrangement was conveniently applied to the construction of trisubstituted allylic alcohols, α,β-unsaturated esters, amides, or ketones in good to excellent chemical yields with exclusive E selectivities.
