4DescriptionAbstract The combination of multicomponent reactions as potential synthetic processes with ionic liquids as catalysts and water as reaction medium is a suitable approach that respects, in some extent, the requirements of sustainable chemistry. In this context, we describe herein an efficient and high yielding four-component synthesis of 6-amino-4-alkyl/aryl-3-methyl-2,4-dihydropyrano[2,3-c]pyrazole-5-carbonitriles involving ethyl acetoacetate, hydrazine hydrate, malononitrile, and various aldehydes using methyltriphenylphosphonium bromide as calalyst and water as solvent under mild reaction conditions.
