A facile and efficient method for one-pot N-alkylation of nucleobases and azole derivatives from alcohols using triphenylphosphine in carbon tetrachloride is described. In this method, treatment of alcohols with a mixture of triphenylphosphine, carbon tetrachloride, nucleobase or azole derivatives and potassium carbonate in the presence of catalytic amounts of tetra-n-butylammonium iodide (TBAI) in
描述了一种在三氯化碳中使用三苯基膦对醇进行的核碱基和唑衍生物的一锅N-烷基化的简便有效方法。在这种方法中,在催化量的四正丁基碘化铵(TBAI)存在下,在回流的N,N-二甲基甲酰胺中,用三苯基膦,四氯化碳,核碱基或唑衍生物和碳酸钾的混合物处理醇,得到了相应的N-烷基衍生物,收率高。该方法学对于各种结构多样的伯醇是高效的,并且也可用于含有酸性NH键的其他N-杂环的N-烷基化。 碳环核苷-N-烷基化-核碱基-醇-三苯膦-四氯化碳-碳酸钾
