A green reaction of isatins, active cyanomethanes, and cyclic 1,3-dicarbonyl derivatives for the efficient and simple one-potthree-componentsynthesis of spirooxindole fused heterocycles in refluxing water by use of magnetically recoverable and reusable catalyst is reported. The features of this procedure are, the use of magnetically recoverable and reusable catalyst, mild reaction conditions, high

highly efficacious synthetic route has been developed for the synthesis of spiro[indoline-3,9′-xanthene]trione and spiro[chromene-4,3′-indoline]-3-carbonitrile derivatives using graphene oxide-supported dicationic ionicliquid (DIL@GO) as a heterogeneous catalyst in aqueous media. Targeted spiro[indoline-3,9′-xanthene]trione derivatives were synthesized via one-pot condensation of substituted isatins

A clean, simple, one-pot, three-component synthesis of some important spirooxindole derivatives in the presence of tetrabutylammonium bromide (TBAB) was carried out under green and environmentally benign conditions.
An efficient, three-component synthesis of spiro[benzo[<i>g</i>]chromene-4,3â²-indoline]-3-carbonitrile and spiro[indoline-3,5â²-pyrano[2,3-<i>d</i>]pyrimidine]-6â²-carbonitrile derivatives
Abstractmagnified image Spiro[benzo[g]chromene‐4,3′‐indoline]‐3‐carbonitriles and spiro[indoline‐3,5′‐pyrano[2,3‐d]pyrimidine]‐6′‐carbonitriles were synthesized via a three‐component reaction of isatins, 2‐hydroxynaphthalene‐1,4‐dione or 2‐methylpyrimidine‐4,6‐diol, and malononitrile in aqueous media.
