with 6-azauracil or N -benzoyladenine followed by condensation with trimethylsilyl triflate in acetonitrile at 80° affords the corresponding persilylated nucleosides. Transsilylation with methanol and chromatography on SiO2 give the pure free nucleosides in up to 70% yield.
将过量的D-核糖或D-葡萄糖与6-氮杂嘧啶或N-苯甲酰腺嘌呤进行全硅烷基化,然后与三氟甲磺酸三甲基甲硅烷基酯在乙腈中于80°缩合,得到相应的全硅烷基化的核苷。用甲醇进行硅烷基化并在SiO 2上进行色谱分离,可得到纯净的游离核苷,收率高达70%。
