Nucleosides in flow: A general, scalable method of Brønsted acid‐catalyzed nucleoside formation is described. Because of the high reaction temperatures readily available to the flow reaction format, mild Brønsted acids, particularly pyridinium triflates, can be used. A one‐flow multistep synthesis of unprotected nucleosides is also reported (see scheme).
流动的核苷:描述了布朗斯台德酸催化核苷形成的通用,可扩展方法。由于流动反应形式易于获得的高反应温度,可以使用温和的布朗斯台德酸,尤其是吡啶鎓三氟甲磺酸。还报道了无保护核苷的单流多步合成(参见方案)。
