フロンティア軌道論によるペリ環状反応の解析と有機合成化学への応用

A new concept of cyclic conjugation as a modification of the Huckel rule has proven to be useful as a general method of predicting thermal stabilities and electonic peoperties of unsaturated cyclic organic molecules. We have been applying this concept to the design of reagents such as p-benzoquinone and 1, 4-dithins. Pericyclic syntheses are very valuable method for the high stereo-, regio-, and periselective controls, and they could provide a logical assembling of molecules, especially highly strained cage compounds which are available or not available for natural sources. These pericyclic reactions are discussed in terms of frontier molecular orbital theory.
