摘要：

The substitution reaction between lower order cyanocuprates and functionalized Z-vinylic tellurides was investigated. alpha,beta-Unsaturated carbonyl compounds were obtained in excellent yields. Changes in the reaction conditions afforded alpha,beta-unsaturated esters in high diastereoselectivity.
