[ 1 ] - Application of nano TiO2@KSF as an efficient and reusable catalyst for the synthesis of pyrano-pyrimidines
In this work, Nano TiO2@KSF used as an efficient, homogeneous and reusable catalyst for the synthesis of pyrano[2,3-d]-pyrimidinone derivatives via three-component reactions between malononitrile, barbituric acid and various aldehydes in water. The products were formed in high yields within short reaction times. Also, this catalyst can be reused several times without loss of its catalytic activ...
[ 2 ] - Nano TiO2@KSF as a high-efficient catalyst for solvent-free synthesis of Biscoumarin derivatives
An efficient, simple and convenient route is described for the synthesis of biscoumarin (3,3'-(arylmethylene) bis (4-hydroxy-2H-chromen-2-one)) by using of recyclable catalyst TiO2@KSF. In this Method, we synthesis biscoumarin derivatives via 3multi-component reactions (3MCRs) of two equivalent 4-hydroxycoumarin with one equivalent of aromatic aldehydes using 20 mg nano TiO2@KSF as homogeneous ...
[ 3 ] - γ-Fe2O3@KSF: A recyclable catalyst for the efficient synthesis of pyrano-pyrimidinone derivatives
In this work, γ-Fe2O3@KSF as a stable heterogeneous and magnetic catalyst was prepared by the successive coating of γ-Fe2O3 shell on KSF core. The prepared reagent was characterized using different methods including FT-IR, XRD, TGA and SEM techniques and used for the one-pot synthesis of pyrano-pyrimidinone derivatives. All reactions were performed under mild conditions, during short reaction t...
