CuCN-catalyzed allylation of ethyl β-(iodozincio)propionate (1), ethyl β-(bromozincio)butyrate (2), ethyl γ-(iodozincio)butyrate (3), and ethyl δ-(iodozincio)pentanoate (4) with allylic halide or tosylate provides ethyl 5-hexenoates, ethyl 6-heptenoates, and ethyl 7-octenoates in high yields.Regioselectivity of the allylation and the reaction of 3 with propargyl tosylate are also discussed.
