    • The invention is a de novo synthesis of the norcatharanthine moiety of navelbine. The synthesis includes condensing a Grignard reagent prepared from an amine-protected R(+)-piperidinyl methanol with an N-protected 2-methoxyoxalyl indole. The indole N-protecting group is removed to provide a 2-methoxyindole hydroxy ester which is coupled to vindoline. After removal of the amineprotecting group from the piperidinyl group, ring closure to the indole moiety provides dihydrodesethyl navelbine. Other derivatives and analogs of navelbine with potential clinical applications in cancer chemotherapy may be readily synthesized. The synthesis opens a route to a wide variety of navelbine modifications, including modifications at or near the tryptamine bridge.
    • 本发明是诺维本的去甲肾上腺素部分的从头合成。 该合成包括将由胺保护的R(+) - 哌啶基甲醇制备的格氏试剂与N-保护的2-甲氧基草酰基吲哚缩合。 除去吲哚N-保护基,得到与维链二氢吡喃偶联的2-甲氧基吲哚羟基酯。 从哌啶基除去氨基保护基后,向吲哚部分的闭环提供了二氢去乙基诺维本。 可以容易地合成其他具有潜在临床应用于癌症化学疗法的衍生物和类似物。 合成开启了各种诺维巴修饰的途径,包括在色胺桥附近的修饰。

    • A process is described for the preparation of the core azobicyclo[7.3.1]tridecaenediyne moiety of the antitumor antibiotic dynemicin. The synthesis allows efficient production of the enediyne as a stable, compound in good yield from the adamantyl N-protected azabicyclo[7.3.1]tridecadiyne. The adamantyl protecting group is employed in the starting material, N-adamantyl dihydroquinoline or N-adamantyl 6-methoxy quinoline. Also disclosed are process for the synthesis of 3-hydroxy-6-methoxyquinoline and several N-substituted derivatives of azobicyclo[7.3.1]tridecaenediyne. Solid tumor and leukemia assays were performed on the analogs of dynemicin. The results suggest a method that these compounds will useful in treating certain types of leukemias and solid tumors. The disclosed synthesis provides a route to new dynemicin intermediates and analogs which will allow development of second and third generation dynemicins.
    • 描述了制备抗肿瘤抗生素dynemicin的核心偶氮二环[7.3.1]十三碳二烯部分的方法。 该合成允许以金刚烷基N-保护的氮杂双环[7.3.1]十三烷二炔作为稳定的化合物有效生产烯二醇。 金刚烷基保护基用于起始原料,N-金刚烷基二氢喹啉或N-金刚烷基6-甲氧基喹啉。 还公开了合成3-羟基-6-甲氧基喹啉和若干N-取代的偶氮二环[7.3.1]十一碳二烯的衍生物的方法。 对dynemicin类似物进行实体瘤和白血病检测。 结果表明这些化合物可用于治疗某些类型的白血病和实体瘤的方法。 所公开的综合提供了新的dynemicin中间体和类似物的途径,其将允许开发第二代和第三代dynemicins。
