Nano-ZnO Catalyzed Multicomponent One-Pot Synthesis of Novel Spiro(indoline-pyranodioxine) Derivatives
A simple catalytic protocol for the synthesis of novel spiro[indoline-pyranodioxine] derivatives has been developed using ZnO nanoparticle as an efficient, green, and reusable catalyst. The derivatives are obtained in moderate to excellent yield by one-pot three-component reaction of an isatin, malononitrile/ethylcyanoacetate, and 2,2-dimethyl-1,3-dioxane-4,6-dione in absolute ethanol under con...
متن کاملSynthesis of spirooxindole derivatives catalyzed by Fe (III)@graphitic carbon nitride nanocomposite via one-pot multi-component reaction
Fe (III) supported graphitic carbon nitride nanocomposite was synthesized by impregnation of FeCl3 with g- C3N4 (Fe (III)@g-C3N4). Then, the synthesis of spirooxindole derivatives was carried out in the presence of Fe (III) @ graphitic carbon nitride nanocompositevia the multi-component reaction of malononitrile, isatins, and 1,3...

متن کاملEfficient one-pot synthesis of pyrazoles catalyzed by nano-crystalline solid acid catalyst
An efficient and green protocol for the synthesis of pyrazoles derivatives by one-pot reaction of different 1,3-dicarbonyl compounds with hydrazines/hydrazides has been developed using nano-sulfated zirconia, nano-structured ZnO, nano-g-alumina and nano-ZSM-5 zeolites, as the catalyst. The optical properties of the nano-structured catalysts and organic molecules were studied. The advantages of ...
