3-Iodoindoles, 5-bromo-3-iodoindoles and 5-bromo-3-iodoindazoles have been studied with respect to their reactivity and selectivity in palladium catalyzed Sonogashira and Suzuki cross-coupling reactions. As a result, sequential Sonogashira-Sonogashira, Sonogashira-Suzuki, and Suzuki-Sonogashira reactions with 5-bromo-3-iodoindoles or indazoles were used to obtain a large range of new functionalized indoles and indazoles, which are potential 5-HT receptor ligands.
对3-碘吲哚、5-溴-3-碘吲哚和5-溴-3-碘吲唑的反应性和选择性进行了研究,尤其是在钯催化的Sonogashira和Suzuki交叉偶联反应中。因此,采用5-溴-3-碘吲哚或吲唑进行了顺序的Sonogashira-Sonogashira、Sonogashira-Suzuki和Suzuki-Sonogashira反应,以获得一系列新的功能化吲哚和吲唑,这些化合物是潜在的5-HT受体配体。
