• 論文の詳細を見る

• The fundamental skeleton of the tropones possessing a unique heptagonal structure is predicted to be aromatic with positive resonance energies and conforming to the topological charge stabilization rule (TCS rule). Similarly, naturally occurring tropolones also nicely fit the theory that conformity to the TCS rule gives a stable molecular system. Thus, many of the troponoids so far synthesized and those occurring in nature are energetically very stable molecules as well as being synthetically very accessible. The TCS rule applies very well to the formation mechanism of heterocycle-fused tropones. It is very likely that there are various reaction paths in nature which are compatible with the TCS rule for the formatin of tropylium compounds having annulated heterocycles.
