An Efficient Solid Phase One Port Synthesis of Novel Triazolo[1,5-a]Pyrimidine Derivatives from 4-(4-Aminophenyl)Morpholin-3-One and Evaluation of their Antimicrobial Activity

Abstract

A series of novel triazolo [1,5-a]pyrimidine derivatives was synthesized from 5-amino-1,2,4-triazole and biologically active morpholinone amine in excellent yield as promising class of antimicrobial agents. The antimicrobial activities were investigated against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Staphylococcus pyogen, Candida albicans, Aspergillusniger, Aspergillusclavatus and compared with standard drugs Ampicillin, Chloramphenicol, Norfloxacin and Griseofulvin. All the synthesized compounds were characterized by IR, 1 H NMR, 13 C and mass spectroscopy. The result of antimicrobial activity data revealed that compound 4f,4g and 4i were found more active against bacterial species and compound 4c, 4d, 4g, 4i and 4jwere found more active against fungal strain, while other compounds shows moderate to law activity against microbes.
