以7-羟基香豆素为原料,在乙醇中与硝酸反应得到了其硝化产物,然后通过Atherton-Todd反应并加入少量的碳酸钾对硝化产物进行了磷酰化反应,得标题化合物。该路线条件温和、操作简单、产率较高,产品的结构均通过NMR、IR、ESI MS和HRMS等确认。
A series of novel 6-nitrocoumarin-7-dialkyl phosphates were synthesized by the Atherton-Todd reaction of 6-nitro-7-hydroxyl coumarin in 48%~77% yields.The structures of the compounds were confirmed by NMR,IR,ESI-MS,and HRMS.
