已经开发出戏剧性的N-取代基控制的2-(2-(2-溴乙基)苯基)-1-磺酰基氮丙啶与1,3-二羰基化合物的串联环化。当N-取代基是4-甲基苯磺酰基(Ts)时,氮丙啶的连续开环,亲核取代和内酰胺化发生,从而以高收率和良好的非对映选择性提供了一系列六氢苯并[ e ]异吲哚化合物。相反,当N-取代基为4-硝基苯磺酰基(Ns)时,通过氮丙啶的开环和亲核取代以高收率获得3-苯并ze庚因化合物。

Two newdibenz[d,f]azoninealkaloids, neodihydrothebaine and bractazonine were isolated from Papaver bracteatum. Their possible biosynthesis from thebaine is discussed. The structures of both newalkaloids are proven by synthesis. An isomeric dibenz[d,f]azonine compound was also prepared.
