合成路线1
该中间体在本合成路线中的序号：(XV)Acylation of (XII) with acetic anhydride and DMAP yielded the 3-acetyl coumarin (XIII). Following desilylation of (XIII) with tetrabutylammonium fluoride to give (XIV), condensation with O-methyl hydroxylamine gave oxime (XV). Treatment of (XV) with p-nitrophenyl chloroformate and DMAP generated carbonate (XVI), which was further coupled with O-propargyl hydroxylamine (XVII) to yield carbamate (XVIII). The tetrahydropyranyl group of (XVIII) was finally deprotected by methanolysis in the presence of p-toluenesulfonic acid.
