a single-step route to access O5′-acetyl ribonucleosides, a key intermediate in the synthesis of biomedically important nucleosides and nucleotides. Moreover, it offered the general applicability of a non-enzymatic method for the selective deacetylation of peracetylated 2′-deoxyribonucleosides. Its synthetic utility was further demonstrated by the synthesis of molecules of biomedical interest by using
通过使用四正丁基氟化铵,在其他乙酸酯官能团存在的情况下,实现了 1,2-二醇二乙酸酯的稳健、温和且高度区域选择性的脱乙酰化。该方法提供了获取 O5'-乙酰核糖核苷的单步途径,O5'-乙酰核糖核苷是合成具有生物医学意义的核苷和核苷酸的关键中间体。此外,它为全乙酰化 2'-脱氧核糖核苷的选择性脱乙酰化提供了非酶促方法的普遍适用性。通过使用这种特殊的脱乙酰反应合成具有生物医学意义的分子,进一步证明了其合成效用。
