The synthesis of 4-functionalized tricyclo[5.2.1.02,6]decenones , starting from furans, is described. These structures are shown to be suitable precursors for the synthesis of cyclopentenoids such as pentenomycin and analogs.

[figure: see text] (+)-Arnicenone, a sesquiterpene of an angular triquinane isolated from Arnica plants, has been synthesized for the first time in an enantiocontrolled manner from a synthetic equivalent of chiral 2-hydroxymethylcyclopentadienone to determine the absolute configuration of the natural product as 1R,3aR,5aS,8aR.

An efficient protocol for the Morita–Baylis–Hillman (MBH) reaction of dicyclopentadienone using CTAB has been developed. The MBH adduct was subsequently transformed to its acetate and bromide derivatives. The 1,3-bielectrophilic character of the MBH acetate and bromide was further explored with various 1,3-binucleophiles to construct various oxa-, thia- and aza-heterocycles. These reactions proceed
