AbstractA simple and efficient protocol was established to synthesize thiazolo[3,2-a][1,3,5]triazin-6-ones via three-component one-pot condensation reaction of readily available thioglycolic acid or ethyl thioglycolate, aldehydes or ketones and dicyandiamide in the presence of ammonium acetate. All of the newly synthesized compounds were characterized by spectroscopic analyses.

Biginelli Condensation

Abstract The simple and efficient synthesis reaction was used for preparing Bis (dihydropyrimidinone) derivatives through Biginelli condensation reaction of terephthalic aldehyde, 1, 3-dicarbonyl compounds and (thio) urea or guanidine and tetrahydro-4H-chromenes via one pot condensation of aromatic aldehydes, malononitrile and dimedone with Ag2O/GO/TiO2 composite nanostructures as a catalyst. The structural functionalities and morphological observations of catalyst were obtained using characterization techniques of field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), Fourier transfer infrared (FT-IR) spectroscopy and transmission electron microscope (TEM). The structures of Bis (dihydropyrimidinone) and tetrahydro-4H-chromenes confirmed by FT- IR, NMR and mass spectroscopy. Excellent yields of the products, simple reaction process and simple work-up are attractive features of these effective synthesis methods.
