    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 The initial six-step development route from 5-fluorouracil has been superseded by a four-step synthesis involving fluorination of methyl 3-oxopentanoate and cyclisation with formamidine acetate.

    Herein we describe structure–activity relationship (SAR) and metabolite identification (Met-ID) studies that provided insight into the origin of time-dependent inhibition (TDI) of cytochrome P450 3A4 (CYP3A4) by compound 1. Collectively, these efforts revealed that bioactivation of the fluoropyrimidine moiety of 1 led to reactive metabolite formation via oxidative defluorination and was responsible
    本文中,我们描述了结构-活性关系(SAR)和代谢物鉴定(Met-ID)研究,这些研究为化合物1对细胞色素P450 3A4(CYP3A4)的时间依赖性抑制(TDI)的起源提供了见识。总的来说,这些努力揭示了1的氟嘧啶部分的生物活化导致经由氧化脱氟的反应性代谢产物形成,并且是观察到的TDI的原因。我们发现,在1的5-氟嘧啶的4和6位上进行取代对于改善该TDI是必要的,如化合物19所示。
