Different synthetic approaches to tricyclo(5.2.1.04,10)decane-2,5,8-trione (2)—a triquinacene derivative especially designed for a convergent and reflexive synthesis of dodecahedrane (1)—have been explored, the acetylenic approach through a Pauson-Khand bis-annulation being the method of choice.
A synthesis of the title compound from Thiele's acid is reported.

transition states involved are of comparable energy. Studies with chiral and racemic 2,3-dihydrotriquinacen-2-one (13) gave analogous results. The various 1,2-glycols are identified by their I3C N M R (symmetry is thereby revealed), ‘H NMR (shielding of the endo protons at Cj and C3, by hydroxyl is witnessed), and ir spectra, in tandem with the method of synthesis.
