Protection-deprotection steps, which are usually needed for regioselective alkylation of pyrimidine deoxynucleosides, can be avoided by choosing the appropriate solvent. The combined effects of low dielectric constant and possible sodium chelation by pyrimidine nucleosides may account for the unexpected regioselectivity observed in THF.
通过选择合适的溶剂,可以避免通常需要进行嘧啶脱氧核苷的区域选择性烷基化的保护-脱保护步骤。低介电常数和嘧啶核苷可能的钠螯合的综合作用可能解释了在THF中观察到的意外区域选择性。
