A general and efficient palladium-catalyzed amination of 5-bromo-3-[2-(diethylamino)ethoxy]indoles has been developed. Best results are obtained in the presence of Pd(OAc)2 and 2-[di(1-adamantyl)phosphanyl]-1-phenylpyrrole as ligand. Subsequent sulfonylation gave novel indole derivatives, which are of interest as potentially biological active 5-HT6 receptor ligands.(© Wiley-VCH Verlag GmbH & Co. KGaA
5-溴-3-[2-(二乙氨基)乙氧基]吲哚的通用且有效的钯催化胺化已被开发。在 Pd(OAc)2 和 2-[二(1-金刚烷基)膦酰基]-1-苯基吡咯作为配体存在时获得最佳结果。随后的磺酰化产生了新的吲哚衍生物,它们作为潜在的生物活性 5-HT6 受体配体很受关注。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
