原始语种摘要: Background: The indole ring system and 4H-Pyran derivatives are significant componentsin many drugs and pharmaceutical agents and spirooxindole containing both indole and pyran ringshave been shown to possess a wide biological and pharmaceutical properties. Methods: We synthesized new derivatives of spirooxindole by a three-component reaction of isatinderivatives, malononitrile (or ethyl cyanoacetate) and beta-dicarbonyl compounds in the presence ofcatalytic amount of N-Phenylpiperazine (NPP) as an organocatalyst. Results: A series of novel derivatives of spirooxindole with potential biological properties were synthesized by a threecomponentreaction in the presence of catalytic amount of N-Phenylpiperazine (NPP) as an organocatalyst. NPP as an efficientcatalyst can be easily handled and...
