A group of homochiral quaternary ammonium sulfonamides bearing hydrophobic camphor derived moieties were synthesized and characterized. The described synthetic procedure is quick and efficient. The novel quaternary ammonium bromides were tested as antimicrobial and antifungal agents. They exhibited strong antimicrobial and also antifungal activity, especially N-{2-[((lS, 4i?)-7,7-dimethyl-2-oxobicy-clo[2.2.1]heptan-l-yl)methylsulfonamido] ethyl}-N,N-dimethy!tetradecan-l-aminium bromide 1c. The surface properties of prepared compounds were evaluated by surface tension measurements and critical micelle concentration (CMC) with surface tension at CMC (ycmc) was calculated.
