Titanium-mediated cyclopropanation of Ξ±,Ξ²-unsaturated esters failed to provide 1-vinylcyclopropanol derivatives in useful yields, but (E)-2-substituted-1-vinylcyclopropanols were formed diastereoselectively from O-protected Ξ²-oxo-and Ξ²halo esters, with the allylic double bond being created subsequen
