- Abstract : Abstract: A newer, versatile, and straightforward synthetic strategy for the construction of functionalized spirooxindole‐pyran annulated heterocycles is described. The procedure is based on CsF‐promoted rapid tandem Knoevenagel‐Michael‐Cyclocondensation reaction of isatin, malononitrile, and 4‐hydroxycoumarin/barbituric acids/pyrazolone at room temperature in ethanol. This methodology has various advantages like easy operational, excellent yields within short reaction time (3‐25 min), and simple isolation of products. The CsF has a dual role as a base and carbonyl activator.
