アジリジン，アゼチジンの環拡大反応を利用したN-ヘテロ環合成法の開発

抄録

In this review we report our recent studies on the synthesis of N-heterocyclic compounds from aziridines and azetidines. The ring expansion reactions of these strained N-heterocycles with various unsaturated compounds such as electron-deficient isocyanates, allenes, and arynes gave five to eight-membered N-heterocyclic compounds efficiently. We also studied the structure as well as the reactivity of some new N-heterocyclic compounds and disclosed their interesting properties.
