Asymetric Epoxidation of Homoallylic Alcohols Using Zirconium Tetrapropoxide, Dicyclohexyltartramide, and t-Butyl Hydroperoxide System

Ikegami, Satoru,Katsuki, Tsutomu,Yamaguchi, Masaru

, p. 83 - 84 (1987)

In the asymmetric epoxidation of homoallylic alcohols, a combination of zirconium tetrapropoxide, dicyclohexyltartramide, and t-butyl hydroperoxide was found to give good enatiometric selectivities ( up to 77percent ee) especially for (Z)-homoallylic substrates.
