The synthesis of the norsesterterpenediacarnoxideC was achieved. The endoperoxide moiety could be prepared in nine and the norsesquiterpene moiety in five steps starting from (E)-3-methyl-6-oxohex-2-en-1-yl acetate and dihydro-β-ionone. The peroxide aldehyde and the norsesquiterpene sulfone were coupled in an (E)-selective Julia-Kocienski reaction. The coupling product was transformed in three additional
