3,4-tetrahydrobenz[f]isoquinoline with ninhydrin leads to annulation of an indeno[1,2-b]pyrrole ring. An analogous product is formed by replacing of the pyrrolidine ring with the piperidine ring. Further heating of the obtained glycol in the presence of AcOH leads to rearrangement with the formation of benz[f]isochromeno-[4',3':4,5]pyrrolo[2,1-a]isoquinoline hexacyclic system.
(4 Z)-2,2-二甲基-4-(2-氧代-2-吡咯烷-1-基亚乙基)-1,2,3,4-四氢苯并[ f ]异喹啉与茚三酮的相互作用导致茚并环化[1,2- b ]吡咯环。通过用哌啶环取代吡咯烷环而形成类似产物。在AcOH存在下进一步加热获得的二醇会导致重排,并形成苯并[ f ]异色素基-[4',3':4,5]吡咯并[2,1- a ]异喹啉六环体系。
