Concerning the Selective Protection of (Z)-1,5-syn-Ene-diols and (E)-1,5-anti-Ene-diols as Allylic Triethylsilyl Ethers
[Image: see text] Treatment of unsaturated 1,5-diols 2 with TES-Cl (1.1 equiv), imidazole, and catalytic DMAP in 1 : 1 CH(2)Cl(2)-DMF at −78 °C effects selective silylation of the allylic alcohol with >95 : 5 chemoselectivity when the allylic and homoallylic alcohols are in similar steric environ...
