Optically Active Antifungal Azoles. VI. Synthesis and Antifungal Activity of N-[(1R, 2R)-2-(2, 4-Difluorophenyl)-2-hydroxy-1-methyl-3-(1H-1, 2, 4-triazol-1-yl)propyl]-N'-(4-substituted phenyl)-3(2H, 4H)-1, 2, 4-triazolones and 5(1H, 4H)-tetrazolones

A new series of optically active antifungal azoles, N-[(1R, 2R)-2-(2, 4-difluorophenyl)-2-hydroxy-1-methyl-3-(1H-1, 2, 4-triazol-1-yl)propyl]-N'-(4-substituted phenyl)-3(2H, 4H)-1, 2, 4-triazolones (1, 2) and 5(1H, 4H)-tetrazolones (3), were prepared from the triflate derivative of (1S)-1-[(2R)-2-(2, 4-difluorophenyl)-2-oxiranyl]ethanol (13) by an SN2 displacement reaction with the anion of an azolone (17-19) and subsequent ring-opening reaction with 1H-1, 2, 4-triazole. The optically active oxiranylethanol 13 was synthesized from methyl (R)-lactate in a stereo-controlled manner. The azolones 1-3 prepared showed potent antifungal activities in vitro and in vivo.
