Synthesis of Fused Indoline‐Cyclobutanone Derivatives via an Intramolecular [2+2] Cycloaddition

A serendipitously‐discovered process for the synthesis of heterocyclic products containing a novel fused indoline‐cyclobutanone ring system is reported. This process is believed to take place through in situ generation of a ketene intermediate, followed by intramolecular [2+2] cycloaddition with a p...
