Two series of new 4-aminopyrimido[4,5-b]indole ribonucleosides bearing phenyl or hetaryl group at position 5 or 6 have been prepared by Suzuki or Stille cross-coupling reactions employing X-Phos ligand with (het)arylboronic acids or stannanes. A series of 4-substituted nucleosides has been also prepared by Pd-catalyzed cross-couplings or nucleophilic substitution. Some of these compounds displayed
通过使用X-Phos配体与(杂)芳基硼酸或锡烷的X-Phos交叉偶联反应,制备了两个系列的在5或6位带有苯基或杂芳基的新的4-氨基嘧啶基[4,5- b ]吲哚核糖核苷。 。还已经通过Pd催化的交叉偶联或亲核取代制备了一系列4-取代的核苷。这些化合物中的某些显示出对HCV和登革热病毒的中等抗病毒活性。
