    Process Development of Voriconazole:  A Novel Broad-Spectrum Triazole Antifungal Agent
    摘要:
    In the synthesis of (2R,3S)-2-(2,4-difluorophenyl)-3-(5-fluoro-4-pyrimidinyl)-1-(1H-1,2,4-triazol-1-yl)-2-butanol (voriconazole), the relative stereochemistry is set in the addition of a 4-(1-metalloethyl)-5-fluoropyrimidine derivative to 1-(2,4-difluorophenyl)-2-(1H-1 ,2,4-triazol-1-yl)-1-ethanone, The diastereo-control of this reaction has been examined by variation of pyrimidine substitution pattern and by changes in the metalation and reaction conditions. Excellent diastereoselection (12: ii is obtained using an organozinc derivative of 6-(1-bromoethyl)-4-chloro-5-fluoropyriminidine. lifter removal cf the chlorine from the pyrimidine ring? the absolute stereochemistry of voriconazole is established via a diastereomeric salt resolution process using (1R)-10 camphorsulfonic acid. Synthetic routes to the pyrimidine partner have also been evaluated. The initial six-step development route from 5-fluorouracil has been superseded by a four-step synthesis involving fluorination of methyl 3-oxopentanoate and cyclisation with formamidine acetate.
