Allylic zirconium reagents were generated by treating allylic ether derivatives with zirconocene “Cp2Zr”. The allylic zirconium reagents reacted with aldehydes in highly regio- and diastereoselective manner to give homoallylicalcohol compounds.
Reactions and characterization of allylic and related zirconium reagents (allenic and γ-alkoxyallylic zirconiums) generated by treatment of allylic and/or propargylic ethers with a zirconocene-butene complex (“Cp2Zr”) are described.

[Structure: see text] A short and efficient synthesis of allylic TBS ethers and allylic alcohols has been developed, based upon a unique Kocienski-Julia olefination reaction. Allylic alcohols and allylicethers are obtained in good to excellent yields and with high (E)-selectivity. The conditions are mild and the procedure is broadly applicable.
