Synthesis of fused 2′-amino-3′-R-spiro-[indole-3,4′-pyran]-2(1H)-ones
摘要:
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.

convenient, and multicomponent strategy for synthesis of spirooxindole derivatives has been developed. This strategy provides a rapid access to construct a diversity‐oriented library of spirooxindoles by using three simple and readily available isatin, malononitrile or cyanoacetic ester, and 1,3‐dicarbonyl compound catalyzed by hexamethylenetetramine in water.
