A one-pot synthesis of a sixfold functionalized dodecahydro-triphenylene 2 with D3 symmetry starting from 1,2,3,4,5,6-hexakis(eq)(ethoxycarbonylmethyl)cyclohexane (1) is described. The new and straightforward approach to this tetracyclic ring system is based on a triple intramolecularly occurring acyloin condensation by using sodium in the presence of chlorotri-methylsilane.
