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 union 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 stereocontrolled manner. The azolones 1-3 prepared showed potent antifungal activities in vitro and in vivo.

An azole compound represented by the formula (I): STR1 wherein Ar is a substituted phenyl group; R1 and R2 independently are a hydrogen atom or a lower alkyl group, or R1 and R2 may combine together to form a lower alkylene group; R3 is a group bonded through a carbon atom; R4 is a hydrogen atom or an acyl group; X is a nitrogen atom or a methine group; and n Y and Z independently are a nitrogen atom or a methine group which may optionally be substituted with a lower alkyl group, or a salt thereof, which is useful for prevention and therapy of fungal infections of mammals as antifungal agent.
