A highly efficient synthesis of γ-halo allylic alcohols and propargylic alcohols with high optical purity. Practical method for synthesis of the prostaglandin ω-chain
Summary: Kinetic resolution of y-trimethylsilyl allylic alcohols 2. by the Sharpless process combined with the reactivity of epoxysilyl or vlnylsilyl compounds affords a highly efficient method for preparation of optically pure y-halo secondary allylic alcohols of type l-4 and propargylic alcohols __ 14. thus providing a practical route to the prostaglandin w-chain.
