Cesium salt of 2-molybdo-10-tungstophosphoric acid as an efficient and reusable catalyst for the synthesis of uracil derivatives: Via a green route

A solid catalyst, cesium salt of 2-molybdo-10-tungstophosphoric acid (Cs2.3H0.7PW10Mo2O40) named as Cs-3, was synthesized by a simple, cheap, clean, and eco-friendly method. The physicochemical properties of the synthesized catalyst were studied via FTIR

Agar-entrapped sulfonated DABCO: Agelly acidic catalyst for the acceleration of one-pot synthesis of 1,2,4-triazoloquinazolinone and some pyrimidine derivatives

In this project, a recently synthesized DABCO-based catalyst is entrapped in agar to reduce its moisture sensitivity leading to enhancement of its stability and catalytic activity. After preparation and identification this new reagent is used as an efficient and environmentally safe catalyst for the preparation of 1, 2, 4-triazoloquinazolinone and some pyrimidine derivatives. This method is accompanied with some superiorities such as, simple operation, mild and green conditions, use of low cost and non-hazardous natural material, short reaction times, easy preparation methods and simple work-up procedures. The prepared catalyst can be re-used for several times in all of the studied reactions without any appreciable loss in its activity.

An eco-friendly and magnetized biopolymer cellulose-based heterogeneous acid catalyst for facile synthesis of functionalized pyrimido[4,5-b]quinolines and indeno fused pyrido[2,3-d]pyrimidines in water

Abstract: A cellulose-based magnetic nano-composite supported SO3H group was synthesized and characterized using Fourier transform infrared spectroscopy, energy-dispersive X-ray spectroscopy, thermogravimetric analysis, X-ray diffraction, and scanning electron microscopy. Thereafter, its capability to promote the one-pot, three-component synthesis of pyrimido [4,5-b] quinolone and pyrido [2,3-d] pyrimidine derivatives was evaluated. The obtained results are indicative of excellent yields and short reaction times. The biopolymer based catalyst is readily recovered and reused several times without a decrease in yield.
