Temperature‐Dependent Regiodivergent [3 + 2] Cycloaddition of Azomethine Ylides With (E)‐5‐Benzylidenethioxoimidazolidin‐4‐One

An efficient route is developed to gain access to novel dispiro[imidazolidine‐4,1′‐pyrrolo[2,1‐a] isoquinoline‐3′,3″‐indoline]‐2″,5‐dione skeletons by a one‐pot three‐component [3 + 2] cycloaddition reaction of (E)‐5‐benzylidenethioxoimidazolidin‐4‐ones, isatin derivatives, and 1...
