Synthesis and properties of new fused pyrrolo-1,10-phenanthroline type derivatives

New fused pyrrolo-phenanthroline type derivatives were synthesized, in two steps, from 1,10-phenanthroline and evaluated for antimicrobial activity fluorescence properties. Our synthetic approach involved a 3+2 dipolarcycloaddition of some selected N-substituted 1,10-phenanthrolin-1-ium ylides, (m)ethoxycarbonyl cyano (1,2-di)substituted acetylenes alkenes, respectively. The structures compounds supported by analytical spectroscopic data. molecular four have also been determined monocrystal XRD analyses. All synthesized then their potential against Staphylococcus aureus ATCC25923, Escherichia coli ATCC25922 Candida albicans ATCC10231. Two the demonstrated significant above tested strains.
