  摘要：

  New duocarmycin SA derivatives have been synthesized and evaluated for in vitro anticellular activity against HeLa S-3 cells, and in vivo antitumor activity against murine sarcoma 180 in mice. The results suggested that the N,N-dialkylcarbamoyl derivatives bearing the p-methoxy cinnamoyl group, which was prepared from duocarmycin SA, showed good in vivo antitumor activities superior to native duocarmycin SA.

  ent-(-)-duocarmycin SA (1) are detailed based on sequential regioselective nucleophilic substitution reactions of the unsymmetrical p-quinone diimine 3 in the preparation of a dihydropyrroloindole precursor to the left-hand subunit. In addition to constituting a new synthetic strategy for the preparation of natural or synthetic duocarmycins and related agents, both enantiomers of 2 (N-BOC-DSA) and its

  天然 (+)- 和 ent-(-)-duocarmycin SA (1) 的简明全合成基于不对称对醌二亚胺 3 在制备左侧二氢吡咯并吲哚前体的顺序区域选择性亲核取代反应亚基。除了构成用于制备天然或合成双癌霉素和相关试剂的新合成策略外，该方法还提供了 2 的对映异构体 (N-BOC-DSA) 及其直接合成前体。这提供了合成类似物的途径，该类似物结合了极其稳定和有效的 duocarmycin SA 烷基化亚基的任一对映异构体。研究中详细介绍了这些试剂的比较化学性质，表明 2 比 N-BOC6CPI（CC-1065 的真实烷基化亚基）对化学溶剂分解更稳定，并且这些试剂参与立体电子控制的溶剂分解反应，亲核加成到受阻最小的环丙烷碳上。与这种增强一致，(+)-2 被证明具有迄今为止检测到的所有天然和合成烷基化亚基（包括 (+)-N-BOC-CPI）中最有效的固有细胞毒性活性，并且其相对细胞毒性效力可预

  Total synthesis of duocarmycin SA (1), an extremely potent cytotoxic antibiotic, was achieved in the racemic form at first by effectively utilizing two reactions as key steps, (i) an intramolecular Heck reaction of the benzyl ether 21a, derived from a dihydropyridine 13a and a pyrrole derivative 11, to form tricyclic compounds 25a and 26a, and (ii) a modified Mitsunobu reaction on the diol derivative 40 for the construction of compound 41 having the pivotal pharmacophore of a cyclopropanoindolinone partial structure, which is critical for the high biological activities of 1. Next, optical resolution of an intermediary racemic secondary alcohol 50 was cleanly attained by derivatizing it to (R)-O-methylmandelates 52 and 53, and the resulting chiral alcohols (+)-50 and (-)-50 were respectively transformed into unnatural (-)-1 and natural (+)-1. Finally inversion of the secondary alcohol (+)-50 to the enantiomer (-)-50 was effected by using the Mitsunobu reaction. This constitutes an enantio-convergent total synthesis of natural duocarmycin SA (1) starting from a racemic compound.

  二氧卡米新SA（1）的全合成首先以外消旋形式实现，通过有效利用两个反应作为关键步骤：（i）从二氢吡啶13a和吡咯衍生物11衍生的苄基醚21a进行的分子内Heck反应，以形成三环化合物25a和26a，以及（ii）对醇衍生物40进行的改进Mitsunobu反应，以构建具有环丙烷吲哚啉酮部分结构的关键药效团的化合物41，这对1的高生物活性至关重要。接下来，通过将中间的外消旋次级醇50衍生化为(R)-O-甲基曼德酸盐52和53，干净地实现了光学分离，得到的手性醇（+）-50和(-）-50分别转化为非天然的(-)-1和天然的(+)-1。最后，通过使用Mitsunobu反应实现了次级醇(+)-50到其对映体(-)-50的倒转。这构成了以外消旋化合物为起始材料的天然二氧卡米新SA（1）的对映体收敛全合成。
