(Chemical Equation Presented) The four olefin stereoisomers of farnesol have been synthesized from readily available nerylacetone or commercial geranylacetone. A new variation on the use of β-oxido ylides favored the (2Z)-stereoisomers, whereas the (2E)-isomers were obtained through a classical Horner-Wadsworth-Emmons condensation with triethyl phosphonoacetate and reduction of the resulting ester.

Hydroprene was obtained with an overall yield of 16percent in the form of a 77:23 mixture of 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.
