Convenient Synthesis of Dihydrobenzofuran-Fused Spirocyclopentane-1,2-Diindolinone Scaffolds
A convenient synthetic protocol for diverse functionalized dihydrobenzofuran-fused spirocyclopentane-1,2-diindolin-ones with high diastereoselectivity is developed by base promoted domino annulation reaction of MBH carbonates of isatins and 3-(o-hydroxybenzylidene)indolin-2-ones. The relative configurations of the various polycyclic compounds are clearly elucidated by determination eight single crystal structures.
