A new approach to synthesis of substituted alkenes is always of interest in synthetic organic chemistry, specifically in the area of natural product synthesis such as terpenes1 and prostaglan- dins2 when reaction conditions are deemed inefficient or inap- propriate by conventional methods. The preparation of , -unsaturated carbonyl compounds using organocuprates by 1,4-addition to unsaturated compounds bearing leaving groups such as halogen,3 ...
