New optically active antifungal azoles, 1-[(1R, 2R)-2-(2, 4-difluoro- and 2-fluorophenyl)-2-hydroxy-1-methyl-3-(1H-1, 2, 4-triazol-1-yl)propyl]-3-(4-substituted phenyl)-2(1H, 3H)-imidazolones (1, 2) and 2-imidazolidinones (3, 4), were prepared in a stereocontrolled manner from (1S)-1-[(2R)-2-(2, 4-difluoro- and 2-fluorophenyl)-2-oxi-ranyl]ethanols (15, 16). Compounds 1-4 showed potent antifungal activity against Candida albicans in vitro and in vivo, as well as a broad antifungal spectrum for various fungi in vitro. Furthermore, the imidazolidinones, 3b-e and 4d, e, were found to exert extremely strong growth-inhibitory activity against Aspergillus fumigatus.
