The title compound was synthesized from 2,4 difluoro α (1 H 1,2,4 triazol 1 yl) acetophenone by phase transfer catalytic reaction with trimethyl sulfoxonium iodide. Total yield of this improved method was 42%.
Eleven 1-(1H-1,2,4-triazole)-2-(2,4-diflurophenyl)-3-(N-methyl-N-substituted benzylamino)-2-propanols were designed and synthesized, on the basis of the crystal structure of P450 cytochrome 14α-sterol demethylase(CYP51) and the docking results of inhibitors to the active site of the enzyme. All title compounds were first by reported. Results of preliminary biological tests showed that most of title compounds exhibited activity against the seven common pathogenic fungi. Compound 11 showed best antifungal activity with broad antifungal spectrum and proved to be more active against Cryptococcus neoformans, Candida albicans, Microsporum lanosum and Trichophyton rubrum than ketoconazole. Compounds 3, 10 and 4 also had high activities.
