The azirines (6) and (7) are shown to be anchored in solution in the conformations shown: it is suggested that these and the envelope conformations in (1)–(4) are stabilised by an interaction between the quinazolone nitrogen (N-3) p-orbital and a (bonded) p-orbital on the adjacent azirine carbon atom (the spiro-centre in (1)–(4) and (6)).
所示的叠氮基(6)和(7)在溶液中锚定为所示构象:建议通过(1)–(4)中的这些构象和包膜构象通过喹唑酮氮(N- 3)p轨道和相邻的叠氮碳原子(在(1)–(4)和(6)中的螺中心)上的p轨道和(结合的)p轨道。
