A bioglycerol derived carbon-sulfonic acid is found to catalyze efficiently the three-component one-pot condensation of isatin, malononitrile, and 1,3-dicarbonyls to afford a wide range of spiro[4H-pyran-3,3′-oxindole] derivatives in good yields and selec

An efficient one-pot procedure has been proposed for the synthesis of fused 2′-amino-3′-R-spiro-[indole-3,4′-pyran]-2(1H)-ones via base-catalyzed three-component condensation of isatins with the corresponding nitriles and 1,3-diketones.
