Staudinger reaction of 9 with triphenylphosphine gave 2,4-dihydropyrrolo[3,4-b]indole 10. Treatment of 10 with di-tert-butyl dicarbonate and 4-dimethylaminopyridine gave 11. Diels-Alder reaction of 11 with 3,4-pyridyne gave cycloadducts 12 and 13, which were converted into ellipticine 1 and isoellipticine 2. New amino analogues of ellipticine 27 and 28 were also synthesized by this new route.
9与三苯基膦的斯托丁格反应得到2,4-二氢吡咯并[3,4- b ]吲哚10。的治疗10与二-叔丁基酯和4-二甲氨基吡啶,得到11。11与3,4-吡啶的Diels-Alder反应生成环加合物12和13,它们分别转化为玫瑰树碱1和异玫瑰树碱2。玫瑰树碱27和28的新的氨基类似物也通过该新途径合成。
