The synthesis of a series of polyfluoromethyl-substituted pyrimidines and pyrazoles bearing potential for further functionalization of the hydroxymethyl group prepared from the fluoroalkyl-containing enones with isothioureas, amidine and hydrazines, is reported. We investigated the deoxyfluorination of hydroxymethyl group in polyfluoromethyl containing pyrazoles and obtained di- and trifluoromethyl
报道了一系列多氟甲基取代的嘧啶和吡唑的合成,它们具有进一步官能化羟甲基的潜力,这些羟甲基是由含氟烷基的烯酮与异硫脲、脒和肼制备的。我们研究了含吡唑的多氟甲基中羟甲基的脱氧氟化,并获得了带有额外单氟甲基的二氟甲基吡唑和三氟甲基吡唑。
