, p. 25625 - 25633 (2015)
A simple, efficient, and eco-friendly procedure for the synthesis of a wide range of pyrazoles bearing a coumarin unit has been developed using a one-pot three-component reaction of salicylaldehyde, 4-hydroxy-6-methyl-2H-pyran-2-one, and hydrazine using m

A synthetic method is described to produce some chromenone-pyrazole derivatives through a one-pot multicomponent reaction using SrFe12O19 as a magnetic catalyst. This method provides quite a few merits, including the use of an effect
Synthesis of 3-(3-methyl-1-aryl-1H-pyrazol-5-yl)-2H-2-chromen-2-one derivatives via a one-pot, three-component reaction

An efficient synthesis of 3-(3-methyl-1-aryl-1H-pyrazol-5-yl)-2H-2-chromen- 2-one derivatives by the reaction of salicylaldehydes, 4-hydroxy-6-methyl-2H- pyran-2-one, and arylhydrazine in acetonitrile under reflux condition and in the presence of piperidine is reported. This three-component reaction has some advantages such as ease of handling, good yields, and easy purification. All structures were confirmed by infrared, mass, 1H NMR, and 13C NMR spectroscopy.
