Popis:	Propylamine functionalized nanoporous silica (SBA-Pr-NH2) has been used as an efficient heterogeneous solid basic nanoreactor in the synthesis of 6'-amino-1'H-spiro[indoline-3,4'-pyrano[2,3-c]pyrazol]-2-one derivatives 5 through one-pot, four component condensation of isatin derivatives 1, activated methylene reagents 2, hydrazine hydrate 3 and β-keto esters 4 under solvent free conditions at room temperature
