Synthesis and characterization of Fe3O4@THAM-SO3H as a highly reusable nanocatalyst and its application for the synthesis of dihydropyrano[2,3-c]pyrazole derivatives

In this work, a new, green and beneficial nanomagnetic catalyst was easily fabricated using sulfuric acid as an acidic group on Fe3O4 nanoparticles coated with tris (hydroxymethyl) aminomethane (THAM). The synthesized catalyst was characterized by FT-IR, TGA/DTG, XRD, TEM, EDS, VSM, and SEM analyses. Next, its catalytic activity was studied for the synthesis of dihydropyrano[2,3-c]pyrazole derivatives. This catalyst has advantages such as high catalytic activity, non-toxicity, easy separation from the reaction mixture using an external magnet and reuses for several times without significantly reducing in its catalytic activity.

A concise route for the one-pot multi-component synthesis of 4,6-disubstituted 2-aminopyridine-3-carbonitriles and pyranopyrazoles using cobalt (II) nitrate hexahydrate as catalyst

Three facile and efficient routes for one-pot, cobalt (II) nitrate hexahydrate catalyzed multi-component synthesis of 2-amino-3-cyanopyridine and pyranopyrazole derivatives have been developed. The present protocols offer the products in good yields from the simple and readily available starting materials. The other salient features of these protocols are operational simplicity, easy isolation of product without the need of column chromatographic purification, and the use of cobalt (II) nitrate hexahydrate as an efficient catalyst.
