A simple and versatile Re-catalyzed Meyer-Schuster rearrangement of propargylic alcohols to α,β-unsaturated carbonyl compounds

Insummary, using the readily available [ReOCl3(OPPh3)DMS)] complex we have developed a new general catalytic procedure for the rapid and efficient 1,3-rearrangement of free secondary alcohols to the corresponding alpha-beta usatured carbonyl compounds with virtually complete E stereoselectivity
