Stereoretentive introduction of (E)- and (Z)-γ-alkoxyallyl groups into carbonyl compounds via light-promoted reaction with γ-alkoxyallylstannanes

Abstract

The light-promoted condensation between carbonyl compounds and (E)- or (Z)-γ-alkoxyallylstannanes affords predominantly the linear homoallylic alcohols, with retention of the double bond geometry of the γ-alkoxyallyl moieties.
