This disclosure is related to halonium compounds useful for cyclization of polyenes, alkenoic acids, and alkenyl alkyl ethers, and halogenation of aromatic compounds. The synthesis of such halonium compounds, compounds made using such halonium compounds, and synthesis of natural compounds, including decalins, using the halonium compounds is also disclosed. A representative halonium compound of the disclosure is: Formula (I).

(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.
