(1H-1,2,4-Triazolyl) methy-4-(sub). phenyl-5-methyl-1,3-dioxolan-2-yliden (3) derivatives were synthesized and tested for their antifungal activities. The designed compounds with a 1,2,4-triazolylmethyl group at the 4-position of 1,3-dioxolan-2-yliden moiety were synthesized by reaction of difluorinated olefins(2) with (2R, 3R)-2-(2,4-dihalophenyl)-1-(1H-1,2,4-triazol-l-yl) butane-2,3-diol (1). These compounds were tested for in vitro antifungal activities against 16 fungi species. The MIC values were determined by the micro broth dilution method. In general, 1,3-dioxolan-2-yliden derivatives showed antifungal activities in vitro. Among them, (4R, 5R)-4-(2,4-difluorophenyl)-5-methyl-2-[1-(3,4-methylenedioxypheny)meth-ylidene)-1,3-dioxolon-4-yl(1H-1,2,4-triazollyl)methane showed superior antifungal activities to fluconazol and ketoconazol.
