1-azoniabicyclo [4.1.0] heptane tosylate gibi bicyclic aziridinium iyonları oluşturulan 2-[4-tolenesulfonyloxybutyl] yerine piperidines ve azepanes yolu ile regio - ve stereospecific hazırlanması için kullanılan aziridin Yüzük-genişleme ile çeşitli nucleophiles. Bu son derece verimli iletişim kuralı çeşitli azaheterocycles fagomine, febrifugine Analog ve balanol gibi doğal ürünler de dahil olmak üzere hazırlamak izin verdi.
