2-dihydrospiro[(3H)-indole-3,4′-(4′H)-pyran]-2-ones has been suggested consisting in the three-component reaction of isatins, cyanoaceticacid derivatives, and α-methylenecarbonyl compounds (β-dicarbonyl compounds, activated phenols, and OH-substituted heterocycles) in ethanol in the presence of triethylamine as a catalyst. The reaction proceeds selectively to form spiro[(3H)-indole-3,4′-(4′H)-pyrans].

Abstract A series of novel oxo-spiro chromene Schiff’s bases were synthesized by condensing 2,7-diamino-2'-oxospiro[chromene-4,3'-indoline]-3-carbonitrile, and series of aromatic aldehydes. Spectrochemical techniques have corroborated the formation of desired products. Derivatives were screened in vitro for antibacterial and anticancer activities. Molecular docking analysis was also performed to predict
