Three-membered-ring-based molecular architectures

An overview is given of the wonderful world of molecular assemblies containing more than one cyclopropane ring. Topics covered include linear aggregates of cyclopropane rings, branched aggregates of three-membered rings and cage structures with three-membered rings. The first covers 1,2-linked oligocyclopropyl systems, oligocyclopropenyl systems, fused systems, 1-1-linked oligocyclopropyl systems and spiroannelated systems-linear triangulanes and heteroanalogues. The second includes oligocyclopropyl-substituted carbo- and heterocycles, branched triangulanes and heteroanalogues, oligospirocyclopropanated carbo- and heterocycled as well as cyclic triangulanes. Finally, the last one focuses on cages incorporating three-membered rings, cages and half-cages with annelated three-membered rings, cages with spiroannelated three-membered rings and cages with three-membered ring substituents.
