As a continuation of our previous studies concerned with the reactivity of benzylidene- and furfurylidenefluorenes in addition reactions, in the present work we have prepared a series of new spiropyrrolidines by reactions of 9-arylmethylenefluorenes I with aryl- (II) and furylazomethines (IV) and some Michael addition products by using diphenylmethyleneazomethines VI and VIII. The structure B was assigned to the furylspiropyrrolidines Va - Vf based on 1H NMR data.
作为我们之前研究的延续,关于苄亚甲基和
呋喃亚甲基
芴在加成反应中的反应性,本研究中我们通过对9-芳基亚甲基
芴I与芳基II和
呋喃亚甲基IV以及二苯亚甲基亚甲基VI和VIII的反应制备了一系列新的螺环
吡咯烷化合物。基于1H NMR数据,将结构B赋予了
呋喃螺环
吡咯烷化合物Va-Vf。
