The bis-Wittig reaction with ɑ-dicarbonyl compounds has been used to prepare cyclopentadienes for subsequent use in the Diels-Alder reaction: J. Am. Chem. Soc., 111, 2351 (1989). For use in the synthesis of open-chain or cyclic polyenes, see: Liebigs Ann. Chem., 619, 10 (1958). Reaction with geranylacetone provides a one-step synthesis of norsqualene: Synthesis, 22 (1970)./n
