Topologically nonplanar hydrocarbons 2 and 3 are available from triptindantrione 1 in only a few steps. Threefold addition of PhLi to 1 and subsequent cyclodehydration provides 2 . In contrast, threefold addition of LiCCR leads surprisingly to a centrohexacyclic tris(enol ether), which can be isomerized thermally into the corresponding triketone.
