Liquid phase tandem Knoevenagel-Michael condensation of various aromatic and heteroaromatic aldehydes with barbituric acid or 2-thiobarbituric acid and malononitrile was studied in a one-pot three-component reaction. For the first time, TMDP was employed as a safe and efficient solvent and/or catalyst in the liquid and aqueous ethanol medium, respectively, for the practical and eco-friendly Knoevenagel-Michael condensation. The reactions were carried out by using greener procedures, including a) the use of TMDP as an N-heterocycle organocatalyst in a green medium including water and ethanol (1:1 v/v) at reflux temperature, and b) the use of TMDP as a dual solvent-catalyst at 65 °C in the absence of any solvent. High to excellent yields of the desired pyrano[2,3-d] pyrimidinones were obtained under the two earlier mentioned conditions. The current methodologies have advantages, including (a) avoiding hazardous, toxic, volatile, and flammable materials and solvents, (b) avoiding tedious processes, harsh conditions, and multiple steps for the preparation of catalysts, (c) using a less toxic and noncorrosive catalyst, (d) minimizing hazardous waste generation and simple workup process, and (e) high recyclability of TMDP. Another important result of this work is that the TMDP can be a promising alternative for toxic, volatile, and flammable base reagents such as piperidine and triethylamine in liquid phase organic syntheses owing to its unique properties such as being less toxic, nonflammable, and nonvolatile, and having a low melting point, broad liquid range temperature, high thermal stability, and safe handling and storage.
SCMNPs@Urea/Py-CuCl2: a recyclable catalyst for the synthesis of pyrano[2,3-d]pyrimidinone and pyrano[2,3-d] pyrimidine-2,4,7-trione derivatives

An efficient, simple, and mild strategy for the one-pot multicomponent synthesis of pyrano[2,3-d]pyrimidinone and pyrano[2,3-d]pyrimidine-2,4,7-trione derivatives is described using SCMNPs@Urea/Py-CuCl2 nanoparticles as a reusable heterogeneous magnetic nanocatalyst. The catalyst was characterized using Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), vibrating sample magnetometry (VSM), energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), and scanning electron microscopy (SEM). The SCMNPs@Urea/Py-CuCl2 can be easily collected from the reaction solution by magnetic decantation using a permanent magnetic field and reused in six runs without significant decrease in catalytic activity.
