Amine-functionalized nano-NaY zeolite for the synthesis of N-acetyl pyrazoles and dihydropyrimidines

An efficient base-catalyzed synthesis of dihydropyrimidines and N-acetyl pyrazoles is reported using 1-(2-aminoethyl)piperazine-modified nano-NaY zeolite (ZeSi–AP) under mild and green conditions. The structure of the catalyst was identified by using FT-IR, XRD, TGA, DTA, DLS, SEM, TEM, and elemental analyses. This heterogeneous catalyst has many benefits, such as a simple work-up procedure, high product yield, and it is easily regenerated and reused at least for four cycles without losing its activity.

Synthesis of some new n-acetylated pyrazoline derivatives via the efficient one-pot reaction by using p-toluenesulfonic acid

A series of a new class of N-acetylated pyrazoline derivatives were synthesized by treatment of chalcones with hydrazine hydrate and acetic anhydride or oxalic acid in the presence of the catalytic amount of p-toluenesulfonic acid in ethanol. All synthesized products were characterized by FT-IR, 1H, and 13C NMR spectral data and elemental analyses. Some advantages of this protocol are a simple work-up procedure, timeconsuming reaction and good to high yields.

Solvent-free synthesis of some1-acetyl pyrazoles

Some N-acetyl pyrazoles including 1-(3-(3,4-dichlorophenyl)-5-(substituted phenyl)-4,5-dihydro-1H-pyrazole-1-yl) ethanones have been synthesised by solvent free cyclization cum acetylation of chalcones like substituted styryl 3,4-dichlorophenyl
