Convenient Synthesis of Dihydrobenzofuran‐Fused Spirocyclopentane‐1,2‐Diindolinone Scaffolds

The diverse functionalized dihydrobenzofuran‐fused spirocyclopentane‐1,2‐diindolin‐one scaffolds were conveniently synthesized by base promoted domino cyclization reaction of MBH (Morita‐Baylis‐Hillmann) carbonates of isatins and 3‐(o‐hydroxybenzylidene)indolin‐2‐ones. The base promoted reactions of...
