[ 1 ] - (CTA)3[SiW12]-Li+-MMT: Efficient nanocatalyst for the synthesis of 3,4-dihydropyrimidin-2(1H)-ones under solvent-free conditions
A highly practical and efficient preparation of 3,4-Dihydropyrimidin-2(1H)-one derivatives was developed via an efficient and simple nanocatalyst and promoted multi-component reaction of ethyl acetoacetate, aromatic aldehyde, and urea in the presence of a catalytic amount of (CTA)3[SiW12]-Li+-MMT under solvent-free conditions. In comparison to the conve...
[ 2 ] - Synthesis of 14H-dibenzo[a.j]xanthenes using Co@pyr/APTZCMNPs as a novel heterogeneous nanocatalyst
Co@pyr/APTZCMNPs was synthesized, and some of its characteristic analyses, such as Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) and X-ray diffraction (XRD) were investigated. The results indicated that this heterogeneous catalyst was an excellent and reusable system to synthesize of 14H</e...
[ 3 ] - Li(OHCH2CH2NH2)(CF3OAC): A novel and homogeneous acidic ionic liquid catalyst for efficient synthesis of 2-amino-4H-chromene derivatives
The ionic liquid Li(OHCH2CH2NH2)(CF3OAC) was found to efficiently catalyze the three-component reaction between different enols, aldehydes, and malononitrile , leading to rapid synthesis of 2-amino-4H-chromene derivatives in fairly high yields. The catalyst is easily prepared, highly stable, simple to handle and recycled for several times without significant loss of activity. The method is simp...
[ 4 ] - [BMIm]BF4-LiCl: An effective catalytic system for the synthesis of pyrano[3,2-c]chromene and pyrano[4,3-b]pyrone derivatives
An efficient and green method for the synthesis of pyrano[3,2-c]chromene or pyrano[4,3-b]pyrone derivatives is described by using a three-component condensation process of malononitrile, aldehyde, and 4-hydroxycoumarine or 4-hydroxypyrone in [BMIm]BF4-LiCl as an ionic liquid.
[ 5 ] - A green, efficient, and rapid procedure for the synthesis of pyrano[3,2-c] quinoline and pyrano[3,2-c]pyridone derivatives catalyzed by [BMIm]Cl
A highly practical and efficient preparation of pyrano[3,2-c]pyridone and pyrano[3,2-c]quinoline derivatives was developed via an ionic liquid mediated and promoted multi-component reaction of malononitrile, aldehyde, and 4-hydroxyquinolin-2(1H)-one or 4-hydroxy-6-methylpyridin-2(1H)-one. The combinatorial syntheses were achieved for the first time without applying extra activation energy at am...
[ 6 ] - The green synthesis of pyrano[3,2-c]quinoline-2,5-dione derivatives catalyzed by acidic ionic liquid under ultrasound irradiation
Abstract-A novel and efficient method has been developed for the synthesis of pyrano[3,2-c]quinoline-2,5-dione derivatives by the convenient ultrasound-mediated condensation of 4-hydroxyquinolin-2-one with Meldrum’s acid and aldehydes in the presence of a catalytic amount of [HMIm]HSO4 as a green, efficient and reusable acidic ionic liquid medium. The stability of the ionic liquid during the re...
