The acyclic nucleoside 4-chloro-2-(methylthio)-7-[[1,3-bis(benzyloxy)-2- propoxy]methyl]pyrrolo[2,3-d]pyrimidine was aminated, desulfurized with Raney Ni, and then debenzylated to provide the tubercidin analogue 11. Cytotoxicity evaluation against L1210 murine leukemic cells in vitro showed that although the
制备了许多与toyocamycin和sangivamycin在结构上相关的7-[((1,3-二羟基-2-丙氧基)甲基]吡咯并[2,3d-d]嘧啶衍生物以及结核菌素,toyocamycin和sangivamycin的山高核苷。并测试其生物学活性。用1,3-双(苄氧基)-2-丙氧基甲基氯处理4-氨基-6-溴-5-氰基吡咯并[2,3-d]-嘧啶的钠盐,得到化合物3,其未经分离就被溴化为得到4-氨基-5-氰基-7-[[[1,3-双(苄氧基)-2-丙氧基]甲基]吡咯并[2,3-d]嘧啶。尽管催化氢解反应失败,但四氯化苄成功裂解了4的苄基醚官能团,得到4-氨基-5-氰基-7-[((1,3-二羟基-2-丙氧基)甲基]吡咯并[2,3-d] ]嘧啶。氰基6的常规官能团转化提供了许多新的5-取代的衍生物。分别用偏高碘酸钠和硼氢化钠分别处理结核菌素(8a),丰卡霉素(8b)和桑奇霉素(8c),分别得到2',3'
