Photochemical and Thermal Ring Transformations of 8-Oxa-3,4-diaza- and 3,4,8-Triazatricyclo2,6>oct-4-enes

Kurita, Jyoji,Sakai, Hiroichi,Tsuchiya, Takashi

, p. 2887 - 2896 (2007/10/02)

Photolysis of the 8-oxa-3,4-diazatricyclo2,6>oct-4-enes (17) prepared from the 1,2-diazepines (9) via five steps resulted in a ring transformation to give the 2,3-diazabicyclohex-3-enes (20), whereas the 8-aza analogues (18) gave
