摘要：

An efficient approach for the synthesis of pharmacologically important spiro[ indoline-3,4'-pyrano[ 2,3-c] pyrazole] derivatives from tandem, four component reaction of various hydrazines, isatins, beta-ketoesters, and malononitrile or methyl( ethyl) cyanoester in the presence of N, N, N', N'-tetrabromobenzene-1,3disulfonamide [ TBBDA] and poly( N, N'-dibromo-N- ethyl-benzene- 1,3-disulfonamide) [ PBBS] as efficient organocatalysts was reported.
