An efficient one pot four-component synthesis of spiro[indoline-3,4′pyrano[2,3-c]pyrazole] derivatives via electrochemical approach

An efficient, simple and one pot, synthesis of spiro[indoline-3,4′-pyrano[2,3-c]pyrazole] derivative by electrochemically induced condensation of β-keto ester, hydrazine hydrate, malononitrile or ethyl cyanoacetate and isatin in an undivided cell at const

4-Dimethylaminopyridine-catalyzed multi-component one-pot reactions for the convenient synthesis of spiro[indoline-3,4′-pyrano[2,3-c]pyrazole] derivatives

An efficient and clean reaction process was developed for the convenient and cheap synthesis of spirooxindole derivatives. One-pot reactions of isatins, malononitrile (or ethyl cyanoacetate), hydrazine hydrate (or phenylhydrazine), and 1,3-dicarbonyl comp

A clean and one-pot synthesis of spiroindoline-pyranopyrazoles

(Chemical Equation Presented) Piperidine catalyzes efficiently the one-pot, four-component reaction of β-ketoesters, hydrazine hydrate, malononitrile, and isatines in aqueous media. The reaction was done at room temperature and the spiro[indoline-3,4′-pyrano[2,3-c]pyrazole]-5′-carbonitriles were obtained with high yields and purity via an easy work-up procedure. These compounds were also investigated in vitro for antibacterial activities.
