A series of 2-amino-6-(2-oxo-2H-chromen-3-yl)-4-pyridine-3-carbo-nitriles were synthesized by the one-pot, multicomponent reaction of 3-acetyl-coumarin, aromatic aldehydes, malononitrile, and ammonium acetate in acetic acid under microwave irradiation. Th

Zinc oxide-decorated superparamagnetic silica attached to graphene oxide (Fe3O4/SiO2/PTS-GO-ZnO), as a novel nanocomposite, was designed, and its core-shell structure was appropriately characterized by different spectroscopy or microscopy methods and thermal techniques as well as measuring of its porosity and magnetic properties. The catalytic activity of Fe3O4/SiO2/PTS-GO-ZnO, as a reusable heterogeneous catalyst, was investigated for efficient one-pot multi-component synthesis of medicinally important functionalized 2-amino-6-(2-oxo-2H-chromen-3-yl)-4-arylnicotinonitrile derivatives. The significant features of the present procedure are mild reaction conditions, low loading of the catalyst, high to quantitative yields of the desired products, avoiding the use of toxic heavy metals or solvents, simple isolation and purification of the products, and stability as well as reusability of the catalyst after at least six consecutive runs.

, p. 259 - 267 (2016/09/23)
In this work, design, preparation and performance of magnetic cellulose/Ag nanobiocomposite as a recyclable and highly efficient heterogeneous nanocatalyst is described. Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD) pattern, vibrating sample magnetometer (VSM) curve, field-emission scanning electron microscopy (FE-SEM) image, energy dispersive X-ray (EDX) analysis and thermogravimetric analysis/differential thermal analysis (TGA/DTA) were used for the characterization. Then, its activity was investigated in the synthesis of 2-amino-6-(2-oxo-2H-chromen-3-yl)-4-phenylnicotinonitrile derivatives. The main advantages of the reaction are high yields and short reaction times. The remarkable magnetic property of the nanobiocomposite catalyst provides easy separation from the reaction mixture by an external magnet without considerable loss of its catalytic activity.
Iron(III) phosphate as a green and reusable catalyst for the synthesis of 4,6-disubstituted 2-aminopyridine-3-carbonitriles

Condensation reaction of aryl aldehydes, methyl ketones, malononitrile, and ammonium acetate in the presence of the green and recyclable catalyst FePO4 affords the corresponding 4,6-disubstituted 2-aminopyridine-3-carbonitriles. Some new derivatives of these compounds are synthesized. The catalyst can be also recycled and reused several times.
