properly substituted bis(indole) pyrazine, the skeleton of a marine alkaloid dragmacidin D, has been developed. The key steps involved the regioselective introduction of two indole units, using the palladium(0)-catalyzed Suzuki and the Stille cross-coupling reactions sequentially.
已经开发出一种选择性构建适当取代的双(吲哚)吡嗪的直接方法,该双(吲哚)吡嗪是海洋生物碱德拉莫达汀D的骨架。关键步骤涉及依次使用钯(0)催化的Suzuki和Stille交叉偶联反应,对两个吲哚单元进行区域选择性引入。
