Abstract

Preparation of (E)-α, β-unsaturated esters and ketones is an important task in organic synthesis.[1] Such esters and ketones are excellent building blocks for the synthesis of a plethora of synthetic and natural products.[2] The most versatile and widely used methods are the Wittig reaction [3] with aldehydes by using alkoxycarbonylmethylene (triphenyl) phosphoranes and the Horner–Wadsworth–Emmons [4] procedure using trialkyl ...
