Hydroprene was obtained with an overall yield of 16% in the form of 77:23 mixture of the 2E,4E and 2Z,4E isomers by ozonolysis of 1,5-dimethyl-1-cyclooctene and selective transformations of the 4-methyl-1,1-dimethoxy-8-oxononane, including ethoxycarbonylmethylenation of the keto group, alkylation of the formyl group by isopropylmagnesium bromide followed by deoxygenation, and allylic bromination-dehydrobromination. The individual 2E,4E isomer was isolated by HPLC.
