A green and efficient procedure was established to synthesize 1,4-dihydropyridines via one-pot Hantzsch reactions in buffering conditions without the use of organic solvent. In this method, Glycine-HCl buffer solution was used as solvent and catalyst reaction; therefore, using this method has several benefits including high yields, an environmentally friendly procedure, short reaction times, and a simple work-up procedure. All the compounds were characterized by TLC, FT-IR, H NMR and elemental studies.

In this work, new N-substituted 2-aminopyrrole derivatives were synthesized. Initially, some crotonitriles were prepared by condensation of malononitrile with arylmethylketones, which was followed by conversion of them to the bromocrotonitriles. Finally, the synthesis of new N-substituted 2-aminopyrrole derivates were successfully achieved by cyclization of the bromocrotonitriles of (R)-1-phenylethylamine applying Gewald method.

Abstract: : Fe3O4 supported graphene quantum dots (GQDs) (Fe3O4@GQDs) was prepared under microwave irradiation. Piperidine was bound to Fe3O4@GQDs via its reaction with 3-piperidinopropyltrimethoxysilane and piperidine-functionalized Lewis basic nano-catalyst (Fe3O4@GQDs-Pip) was prepared. This freshly prepared catalyst was evaluated as a heterogeneous magnetic reusable catalyst for the one-pot synthesis of 2aminochromenes under MW-assisted solvent-free conditions. Two composite particles, Fe3O4@GQDs and Fe3O4@GQDs-Pip were characterized by FT-IR, XRD, SEM, TGA and VSM analytical methods. The catalyst could be easily recovered by magnetic separation and recycled for 5 times without significant loss of its catalytic activity.

Graphene quantum dots (GQDs) immobilized nanosilica was prepared under microwave irradiated green reaction conditions and was used as an efficient heterogeneous acid catalyst. The structure of nano-catalyst was characterized by FT-IR, PL, TEM, XRD, FE-SEM, EDS, TGA, and zeta potential. Xanthene derivatives were synthesized in excellent yields using the freshly prepared catalyst and the catalyst could be easily recovered and recycled for 5 times without significant loss of its catalytic activity. The structures of the resulted products were confirmed by FT-IR, H-NMR, C-NMR spectroscopic techniques.

Some isoindole-1,3-dione compounds (5, 6, 7, 8, 9, and 10) have been synthesized starting from 3a,4,7,7atetrahydroisobenzofuran-1,3-dione (4). Compounds 5, 6, 7, 8, 9, and 10 were characterized by H and C NMR spectra, FT-IR spectroscopy, and mass spectra measurements. The optical properties of the isoindole-1,3-dione compounds (5, 6, 7, 8, 9, and 10) were also investigated. For this purpose, UV-Vis spectra of these compounds were recorded in CH2Cl2. The absorbance (Abs), transmittance (T), absorbance band edge (EAbs-be), optical band gap (Eg), and refractive index (n) of these compounds were calculated and application areas of these materials were sought.

The synthesis of (E)-10-hydroxy-2-decenoic acid ethyl ester (10H2DA-EE) (3) was achieved via a one-pot, tandem oxidation-Wittig process from commercially available 1,8-octanediol (1), Wittig reagent (Ph3P=CHCO2Et) (2) and activated MnO2. Subsequent hydrolysis with sodium hydroxide gave (E)-10-hydroxy-2-decenoic acid (10H2DA) (4).
