نویسندگان
چکیده
This work concerns the synthesis of poly(pyrazolopyridine)s via a three-component Hantzsch reaction. The first part this study was intended to determine adequate experimental conditions for an analytically pure pyrazolopyridine heterocycle model compound in quantitative yield, which can be further used polymer synthesis. For purpose, effect different parameters (solvent, temperature, additive) on selectivity reaction has been investigated. Some specific difunctional precursors (bisaminopyrazoles and dialdehydes) have then designed synthesized. From these reagents, were successfully synthesized by multicomponent polycondensation physico-chemical characterizations new macromolecular structures are described.

Sulfated titania nanoparticles (SO42-/TiO2 NPs) were synthesized using titanium tetraisopropoxide (TTIP) by the sol-gel method. The structure and morphology of the prepared nanocatalyst was characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM) and Brunauer–Emmett–Teller (BET) methods as well as Fourier transform infrared (FT-IR) and energy dispersive X-ray (EDX) spectr...

The four-component Hantzsch reaction provides access to pharmaceutically important dihydropyridines. To expand the utility of this method, we have developed a route under organocatalytic conditions with good yields and excellent ee's. Through catalyst screening, we found that a BINOL-phosphoric acid allowed enantioselective synthesis of six-membered heterocycles with a variety of substitution p...

The catalytic ability of ZrO(2)/SO(4)(2-) to promote solventless three-component condensation reactions of a diversity of aromatic aldehydes, urea or thoiurea and ethyl acetoacetate was studied. Products resulting from Hantzsch and/or Biginelli multi-component reactions are obtained in the presence of solid acid catalysts using the same reactants but different temperature conditions. The sulfat...
