An Efficient One-Pot Protocol for the Synthesis of Substituted 3,4-Dihydropyrimidin-2(1H)-ones Using Metallophthalocyanines (MPcs) as Potent Heterogeneous Catalysts: Synthesis, Characterization, Aggregation and Antimicrobial Activity. | LitMetric

AI Article Synopsis

Article Abstract

In this study, novel phthalonitrile and their corresponding metal-free and metallophthalocyanine derivatives - bearing 2-isopropenyl-4-methoxy-1-methylbenzene groups were synthesized and characterized. 3,4-Dihydropyrimidinones have been synthesized by a modified Biginelli-type reaction with various metallophthalocyanines - as catalysts. Compared to the classical Biginielli reaction, the new method has the advantages of good yield and short reaction time. Among the various metallophthalocyanines studied, cobalt (II)-phthalocyanine was found to be most active for this transformation. The newly prepared compounds were characterized using elemental analyses, MS, IR, ¹H/C-NMR and UV-Vis spectroscopy. In addition; the 3,4-dihydropyrimidinones (DHPMs) - were investigated for antimicrobial activities and revealed good activity. The minimum inhibitory concentration (MIC) was determined by the microdilution technique in Mueller-Hinton broth. The MICs were recorded after 24 hours of incubation at 37 °C. These results are promising, showing these compounds are biologically active.
