Novel heptacyclic triones 8 and 9 have been synthesised. A series of probing experiments on the heptacyclic ketones 3, 8 and 9, in quest for [7]-prismane homo- and secologues are described. Synthesis of novel polyhedranes 23-25 through thermal 2 + 2-cycloreversion of 3, 8 and 17, respectively, has been achieved. Our results point to the need for devising de novo strategy for the creation of higher prismanic frameworks.
