Halogenated nucleoside derivatives were trifluoromethylated using a solution of a trifluoromethyl–copper complex, which was prepared by shaking trifluoromethyl iodide and copper powder in hexamethylphosphoric triamide and filtering off the excess of copper powder. The following trifluoromethylated nucleosides were obtained in moderate to good yields: 5-trifluoromethyl-uridine, -deoxyuridine, -cytidine
使用三氟甲基-铜络合物的溶液将卤代的核苷衍生物进行三氟甲基化,该溶液是通过将三氟甲基碘和铜粉在六甲基磷酸三酰胺中振摇并滤出过量的铜粉而制得的。以中等至良好的产率获得以下三氟甲基化的核苷:5-三氟甲基-尿苷,-脱氧尿苷,-胞苷,-脱氧胞苷和-阿拉伯糖基胞嘧啶;8-三氟甲基-腺苷,-脱氧腺苷和-肌苷;和6-三氟甲基核呋喃呋喃糖基嘌呤。该程序提供了许多三氟甲基化合物的简单合成方法。
