Furoxans are potentially useful heteroaromatic units in pharmaceuticals and agrichemicals. However, the applications for furoxan-based compounds have been hampered due to the underdevelopment of their synthetic methods. Herein, we report a new synthetic approach for the synthesis of chloro- and bromofuroxans. The starting materials were dichloro- and dibromofuroxans, and the substituents were directly
呋喃喃类化合物在医药和农业化学中是潜在有用的杂芳族单元。然而,由于其合成方法的不发达,基于呋喃喃类化合物的应用受到了阻碍。在这里,我们报告了一种新的合成方法,用于合成氯代和溴代呋喃。起始原料是二氯呋喃和二溴呋喃,并将取代基以模块方式直接引入到呋喃环中。合成的一氟代呋喃并用作安装第二个取代基的底物,以制备进一步的官能化的呋喃喃。
