  Crystal-structure-based design and synthesis of benz[cd]indole-containing inhibitors of thymidylate synthase

  摘要：

  The X-ray crystal-structure-based design, synthesis, and biological activity of a novel family of benz[cd]indole-containing inhibitors of thymidylate synthase (TS) are described. The structure-activity of the lead compound was studied by conceptually dividing the molecule into four regions and independently optimizing the substituents for each region. Combination of favored substituents for each region led to inhibitors with K(i)'s against the human enyzme in the range of 10-20 nM. Thymidine shift experiments suggested that the cytotoxic properties of the best enzyme inhibitors were due to TS targeting in cells. The inhibitors were synthesized from substitued 6-aminobenz[cd]indol-2(1H)-ones by alkylation with both a simple alkyl group and a substituted benzylic portion. The 2,6-diaminobenz[cd]indoles were prepared from the corresponding lactams by conversion to the thiolactam, alkylation to the methylated thiolactam, and then displacement with a substituted or unsubstituted amine.

• Generation of Dithianyl and Dioxolanyl Radicals Using Photoredox Catalysis: Application in the Total Synthesis of the Danshenspiroketallactones via Radical Relay Chemistry

  Visible-light-induced generation of dithianyl and dioxolanyl radicals via selective hydrogen atom transfer (HAT) has been achieved. This radical relay tactic enables remote C(sp3)–H functionalization to permit rapid access to polyol and spiroketal segments, and in turn has been exploited as a key synthetic construct in the total synthesis of the danshenspiroketallactones. The conformational stability

  Carbon dioxide (CO2) is an attractive one-carbon (C1) building block in terms of sustainability and abundance. However, its low reactivity limits applications in organic synthesis as typically high-energy reagents are required to drive transformations. Here, we present a redox-neutral C─H carboxylation of arenes and styrenes using a photocatalytic approach. Upon blue-light excitation, the anthrolate

  就可持续性和丰富性而言，二氧化碳（CO 2）是有吸引力的一碳（C1）构建基块。但是，其低反应性限制了有机合成中的应用，因为通常需要高能试剂来驱动转化。在这里，我们介绍了使用光催化方法的芳烃和苯乙烯的氧化还原中性CH羧基化。在蓝光激发下，邻苯二甲酸根阴离子光催化剂能够将许多芳族化合物还原为相应的自由基阴离子，这些自由基阴离子会与CO 2反应得到羧酸。高通量筛选和计算分析表明，底物的电子亲和力和亲核性之间的正确平衡至关重要。这种新颖的方法使许多芳族化合物能够羧基化，包括许多经典的羧化化学中不容忍的化合物。超过50个使用CO 2或酮进行C-H官能化的例子说明了广泛的适用性。该方法为常见的芳烃的增值提供了新的机会，并可能在后期的CH羧基化中得到应用。
