Abstract

Two new azachalcones were prepared by both Claisen-Schmidt condensation and a simple environmentally trendy microwave-assisted method. Ten new N-alkyl (C-6,C-8,C-10,C-12,C-14)-substituted azachalconium bromides (3a-e, 4a-e) were prepared from compounds 1 and 2 with corresponding alkyl halides. The antimicrobial activities of all the compounds were tested against Enterococcus faecalis, Yersinia pseudotuberculosis, Pseudomonas aeruginosa, Escherichia coli and Staphylococcus aureus micro-organisms.
