A new synthesis of entecavir from d-glucose in an average total yield of 3.5% was achieved via an intramolecular nitrile oxide cycloaddition (INOC) reaction and a Peterson olefination as key-steps. The present process was designed for industrial application, using widely available raw materials, simple and cheap reagents and avoiding low reaction temperatures, which are very common in the synthetic
通过分子内腈氧化环加成(INOC)反应和彼得森烯化反应为关键步骤,由d-葡萄糖合成了恩替卡韦,平均总收率为3.5%。本方法是为工业应用而设计的,它使用了广泛可用的原料,简单且便宜的试剂并避免了低反应温度,这在合成类似结构的复杂方法中非常普遍。
