convenient method for the synthesis of 3-methylthioindoles has been established which does not use smelly compounds such as thiol derivatives. The method, which introduces an alkyl- or arylthio-group into the C(3)-position of the indole skeleton, was extended to the direct introduction of a methylthio or bromo group at the C(2)-position using 3-methylthioindoles. No dimerization occurred, and the reaction
已经建立了不使用臭味化合物例如硫醇衍生物的合成3-甲基硫代吲哚的简便方法。该方法将烷基硫基或芳硫基引入吲哚骨架的C(3)位,该方法扩展为使用3-甲基硫代吲哚在C(2)位直接引入甲硫基或溴基。没有发生二聚反应,并且确认了反应机理。该产品具有从海藻中分离出来的强抗甲氧西林金黄色葡萄球菌(抗MRSA)溴甲基硫吲哚(MC 5-8)的部分结构。此外,该反应可用于合成3,3-二吲哚基硫醚,其是棘孢砜A的核心结构。
