ChemInform Abstract: Asymmetric Synthesis of Bioxindole-Substituted Hexahydrofuro[2,3-b]furans via Hydroquinine Anthraquinone-1,4-diyl Diether-Catalyzed Domino Annulation of Acylidenoxindoles/Isatins, Acylidenoxindoles and Allenoates.

An abstract on a study relating to spirocyclic compounds is presented which describes the asymmetric synthesis of bioxindole furans using hydroquinine anthraquinone-catalyzed domino annulation of acylidenoxindoles, isatins, and allenoates.
