A novel and efficient approach for synthesizing acyclic nucleoside analogues with a side chain length of two carbon atoms has been established. It involves purines reacting with α-keto esters in a P(NMe)-mediated deoxygenation process, yielding the products in high yields and regioselectivities (22 examples, up to 93 % yield, up to >20:1 N/N selectivities). This reaction features short reaction times
已经建立了一种合成侧链长度为两个碳原子的无环核苷类似物的新颖且有效的方法。它涉及嘌呤与 α-酮酯在 P(NMe) 介导的脱氧过程中反应,产生高产率和区域选择性的产物(22 个例子,高达 93% 的产率,高达 >20:1 N/N 选择性)。该反应具有反应时间短、无金属催化、反应条件温和、底物范围广等特点,具有广阔的实际应用前景。
