摘要
以国内已实现批量生产供应的 1b和 1a为原料,经缩合反应制备化合物 1.在碳酸铯的作用下,化合物 1 和 2a发生反应,生成化合物 2.随后,化合物 2 通过与醋酸铵的作用,形成化合物 3.化合物 3 通过氧化脱氢反应,生成重要的化合物 4.将叔丁氧羰基从化合物 4 中脱离出来,可以制备化合物 5.化合物 5 在 2-氯-4,6-二甲氧基-1,3,5-均三嗪作用下与MOC-D-苯甘氨酸进行酰胺缩合反应,得到目标化合物维帕他韦(化合物 6).本合成方法具有路线短,原辅料便宜易得,各步反应条件温和,操作简单、安全等优点.
Abstract
Compound 1 is prepared by condensation reaction using 1b and 1a,which have already been mass-produced and supplied domestically,as raw materials.Under the action of cesium carbonate,compound 1 and 2a react to form compound 2.Subsequently,compound 2 reacted with ammonium acetate to form compound 3.Compound 3 undergoes oxidative dehydrogenation reaction to generate the important compound 4.By separating the tert butoxycarbonyl group from compound 4,compound 5 can be prepared.Compound 5 undergoes amide condensation reaction with MOC-D-phenylglycine under the action of 2-chloro-4,6-dimethoxy-1,3,5-triazine to obtain the target compound vipatavir(Compound 6).This synthesis method has the advantages of short route,cheap and easy to obtain raw materials,mild reaction conditions in each step,simple operation,safety,etc.
