The 3+2 cycloaddition reaction of 1-(4-phenylphenacyl)-1,10-phenanthrolinium ylide 4 with activated alkynes gave pyrrolo[1,2- 4a][1,10]phenanthrolines 6a-d. The "one pot" synthesis of 6a,b,d from 4, activated alkenes, Et(3)N and tetrakis-pyridine cobalt (II) dichromate (TPCD) is described. The helical chirality of pyrrolophenanthrolines 6b-d was put in evidence by NMR spectroscopy.
1-(4-苯基苯甲酰基)-1,10-菲咯啉鎓叶立德4与活化炔烃的3+2环加成反应得到吡咯并[1,2-4a][1,10]菲咯啉6a-d。描述了从 4、活化烯烃、Et(3)N 和四吡啶钴 (II) 重铬酸盐 (TPCD) “一锅法”合成 6a、b、d。吡咯并菲咯啉 6b-d 的螺旋手性通过核磁共振波谱得到证实。
