Opis:: A series of novel 5-(2-bromophenyl)-N-cyclohexyl-2-(methylthio)-6-nitro-7-phenyl-4,7-dihydropyrazolo[1,5-a]pyrimidine-3-carboxamides were synthesized by a one-pot reaction of 5-amino-N-cyclohexyl-3-(methylthio)-1H-pyrazole-4-carboxamide, 1-(2-bromophenyl)-2-nitroethanone and aryl aldehydes in the presence of boric acid in water at refluxing temperature. Structures of compounds were demonstrated by Fourier transform infrared, ¹H NMR, ¹³C NMR and elemental analysis. The advantages of this method are mild reaction condition, good yields, and operational simplicity.

Opis:: An eco-friendly and efficient one-pot synthesis of penta-substituted pyrrole derivatives via a four-component reaction of maldrum’s acid, arylglyoxal monohydrate, dimethyl but-2-yne-dioate and amines under catalyst-free conditions in an environmentally friendly medium is described. The simple experimental procedure, catalyst-free reaction conditions, short period of conversion, and excellent yields are the advantages of the present method. Good chemical yields have been achieved without the need for chromatography and recrystallization or other purification methods.

Opis:: We have demonstrated two step one-pot synthesis of novel 5-(4-Fluorophenyl)-1H-Beno[e][1,4]Diazepin-2(3H)-one using 2-Amino-4’-fluorobenzophenone as initial stating material. The small library of N-alkylation and C-3 benzylidene derivatives have been synthesized by base catalyzedreaction of 5-(4-fluorophenyl)-1H-benzo[e][1,4]diazepin-2(3H)-one (3) nucleus with various alkyl halides and aromatic aldehydes respectively.

multi component reaction
non-chromatographic method
Opis:: A series of pyrimidine-5-carbonitrile derivatives was efficiently synthesized via one-pot, multi component reaction (MCRs) of 1,3-bifunctional synthon (ethylcyano acetate), substituted pyrazole-4-carbaldehyde, and thiourea/urea in the presence of basic catalyst. The key advantages of this process are high yields, shorter reaction times, easy work-up, and purification of products by non-chromatographic method.

Opis:: A green resourceful, eco-friendly and facile protocol was developed for the synthesis of benzylamine coumarin derivatives by the reaction of 4-hydroxy coumarin, secondary amine and aromatic aldehyde in the presence of PEG400 as a solvent as well as catalyst at room temperature. A wide range of functional groups were tolerated in the developed protocol. The structures of all the synthesized compounds were confirmed by 1H NMR, IR, MASS and Elemental Analysis. The target molecules were obtained in good to excellent yield applying this method.
