An efficient synthesis of 2-halo-O6-(benzotriazol-1-yl)-substituted purine nucleosides has been accomplished via (benzotriazol-1-yloxy)tris(dimethylamino)phosphonium hexafluorophosphate (BOP)-mediated coupling and subsequent halogenation via diazotization of the 2-amino group of various protected guanosines and directly from guanosine itself. These products are amenable to substitution and coupling
2-卤代-O6-(苯并三唑-1-基)-取代的嘌呤核苷的有效合成是通过(苯并三唑-1-基氧基)三(二甲氨基)鏻六氟磷酸(BOP)介导的偶联和随后通过重氮化的卤化完成的各种受保护鸟苷的 2-氨基,直接来自鸟苷本身。这些产品适合在 2 位和 6 位进行取代和偶联反应,因此可以有效地获得高度官能化的嘌呤核苷。
