2-Cyano- and 2-carbethoxy-3-[2-(pyrrolidin-1-ylmethyl)phenyl]acrylonitriles were prepared through either amination of appropriate 3-[2-(bromomethyl)phenyl]acrylonitriles with pyrrolidine or condensation of 2-(pyrrolidin-1-ylmethyl)benzaldehyde with malononitrile and ethyl cyanoacetate. These acrylonitrile derivatives were shown to undergo easy mutual interconversion with 1-(pyrrolidin-1-yl)indane-2-carbonitriles
通过用吡咯烷胺胺化适当的3- [2-(溴甲基)苯基]丙烯腈或2-(缩合)缩合制备2-氰基和2-乙氧基-3- [2-(吡咯烷-1-基甲基)苯基]丙烯腈。吡咯烷-1-基甲基)苯甲醛与丙二腈和氰基乙酸乙酯。这些丙烯腈衍生物显示出与由溶剂极性驱动的1-(吡咯烷-1-基)茚满-2-腈容易相互转化。当在140-150℃下加热两丙烯腈和二氢化茚衍生物被发现,得到2,3,5,10,11,11一-六氢- 1 H ^ -吡咯并[1,2- b ] [2]苯并氮杂-11-腈。观察到所有的转化在反应有关的术语进行了合理化叔-氨基效应。此外,类似地获得了上述丙烯腈和茚满的相应的哌啶-1-基和氮杂-1-基类似物。通过类比其加热,得到1,2,3,4,6,11,12,12一个-octahydropyrido [1,2 b ] [2]苯并氮杂-12-腈和7,8,9,10,11,11 a,12,13- octahydro -5
