  Synthesis of Cytotoxic Indenoisoquinoline Topoisomerase I Poisons

  摘要：

  A number of indenoisoquinolines were prepared and evaluated for cytotoxicity in human cancer cell cultures and for activity vs topoisomerase 1 (top1). The two most cytotoxic indenoisoquinolines proved to be cis-6-ethyl-5,6,12,13-tetrahydro-2,3-dimethoxy-8,9-(methylenedioxy)-5,11-dioxo-11H-indeno[1,2-c]isoquinoline (21) and cis-6-allyl-5,6,12,13-tetrahydro-2,3-dimethoxy-6,9-(methylenedioxy)-5,11-dioxo-11H-indeno[1,2-c]isoquinoline (22), both of which displayed submicromolar mean graph midpoints when tested in 55 human cancer cell cultures. Two of the most potent top1 inhibitors were 6-(3-carboxy-1-propyl)-5,6-dihydro-5,11-dioxo-11H-indeno[1,2-c]isoquinoline (26) and 6-ethyl-2,3-dimethoxy-8,9-(methylenedioxy)-11H-indeno[1,2-c]isoquinolinium chloride (27), both of which also inhibited top2, unwound DNA, and are assumed to be DNA intercalators. However, two additional potent top1 inhibitors, 6-allyl-5,6-dihydro-2,3-dimethoxy-8,9-(methylenedioxy)-5,11-dioxo-11H-indeno[1,2-c]isoquinoline (13c) and 5,6-dihydro-6-(4-hydroxybut-1-yl)-2,3-dimethoxy-8,9-methylenedioxy-5,11-dioxo-11H-indeno[1,2-c]isoquinoline (19a), did not unwind DNA and did not affect top2, Some of the DNA cleavage sites detected in the presence of the indenoisoquinolines were different from those seen with the camptothecins. The cleavage sites induced by the indenoisoquinolines were reversed by salt treatment, which is consistent with the reversible trapping of top1 cleavable complexes by the indenoisoquinolines. In general, the potencies of the indenoisoquinolines as top1 inhibitors did not correlate with their potencies as cytotoxic agents, as some of the most cytotoxic agents had little if any effect on top1. On the other hand, the most potent of the indenoisoquinolines vs top1 were not the most-cytotoxic. In several cases, moderate activity was observed for both cytotoxicity and activity vs top1.

  使用外和内选择性自由基环化到酰胺上的含氮杂环的合成

  摘要：

  研究了酰胺的羰基位置变化对Bu 3 SnH介导的烷基自由基环化导致五元，六元，七元和八元含氮杂环的影响。甲5-外型环化通常优选在6-内闭环在具有对烯酰胺酰基侧链的烷基中心系统，而具有的烷基基团中心相对的酰基侧链烯酰胺主要得到6-内环化产物。这些结果表明，exo或endo自由基环化到酰胺的烯键上的选择性可以通过羰基的位置变化来控制。为了理解这些选择性，计算了每个过渡态的形成热。将6-内-选择性自由基环化作用于自由基级联反应，从而实现了cylindricine骨架的简明合成。甲7-或8-内切烷基自由基环化，但是，在占优势的相应的6-或7-外切环闭合无论烯酰胺的羰基的位置变化的。

  1,3-Diamines are an important class of compounds that are broadly found in natural products and are also widely used as building blocks in organic synthesis. Although the intramolecular C−H amination of N-alkylsulfamide derivatives is a reliable method for the construction of 1,3-diamine structures, the majority of these methods involve the use of a transition-metal catalyst. We herein report on a

  1,3-二胺是一类重要的化合物，广泛存在于天然产物中，也广泛用作有机合成中的结构单元。尽管N-烷基磺酰胺衍生物的分子内 C-H 胺化是构建 1,3-二胺结构的可靠方法，但这些方法中的大多数都涉及使用过渡金属催化剂。我们在此报告了一种新的无过渡金属方法，该方法使用叔丁基次碘酸盐 ( t -BuOI) 或N-碘代琥珀酰亚胺 (NIS)，能够进行二次非苄基和叔 C-H 胺化反应。环状磺酰胺产物很容易转化为 1,3-二胺。机理研究表明，胺化反应使用t-BuOI 或 NIS 各自通过不同的途径进行。

  Natural products have long been important inspirations for the development of chemical methodologies, theories, and technologies, and ultimately, discoveries of new drugs and materials. Chemical syntheses have traditionally yielded individual or small groups of natural products; however, methodology development allowing the synthesis of a large collection of natural products remains scarce. Here, we

  长期以来，天然产物一直是化学方法论，理论和技术发展以及最终发现新药物和新材料的重要灵感。传统上，化学合成产生单个或一小群天然产物。但是，仍然缺乏方法学的发展以允许合成大量天然产物。在这里，我们报告了一种有效的光催化自由基级联方法，该方法可以访问手性和多环稠合的四氢咔啉酮的文库。自由基级联可以可控制地将复杂性和功能性引入具有出色的化学选择性，区域选择性和非对映选择性的产品中。这种独特方法的强大功能已通过有效合成属于四个家族的33种单萜类吲哚生物碱得到了证明。

  Primary aliphatic amines are important building blocks in organic synthesis due to the presence of a synthetically versatile NH2 group. N-functionalization of primary amines is well established, but selective C-functionalization of unprotected primary amines remains challenging. Here, we report the use of CO2 as an activator for the direct transformation of abundant primary aliphatic amines into valuable

  由于存在合成用途广泛的NH 2基团，伯脂肪族伯胺是有机合成中的重要组成部分。伯胺的N-官能化是公认的，但是未保护的伯胺的选择性C-官能化仍然具有挑战性。在这里，我们报道了在光氧化还原和氢原子转移（HAT）催化下，CO 2作为活化剂用于将大量的初级脂肪族胺直接转化为有价值的γ-内酰胺的方法。实验和计算研究表明，CO 2不仅可以抑制不想要的N伯胺的-烷基化反应，但也可以通过原位产生的带负电的氨基甲酸酯和带正电的奎宁环鎓自由基之间的静电加速相互作用来促进选择性分子间HAT。这种静电吸引力压倒了固有的键解离能，这表明HAT应该无选择地发生。我们预期我们的发现将为HAT反应中的胺官能化以及选择性控制开辟新途径。

  A method for remote radical C–H alkynylation at unactivated sites is reported. C–H functionalization proceeds via 1,5-hydrogen atom transfer (HAT) to amidyl radicals that are generated via an addition/fragmentation reaction. The readily installed N-allylsulfonyl moiety is used as a precursor of the N-centered radical. Unactivated secondary and tertiary as well as selected primary C–H bonds can be functionalized

  A general and practical strategy for remote site‐selective functionalization of unactivated aliphatic C−H bonds in various amides by radical chemistry is introduced. C−H bond functionalization is achieved by using the readily installed N‐allylsulfonyl moiety as an N‐radical precursor. The in situ generated N‐radical engages in intramolecular 1,5‐hydrogen atom transfer to generate a translocated C radical

  介绍了一种通过自由基化学方法对各种酰胺中未活化的脂肪族CH键进行远程位点选择性官能化的通用和实用策略。通过使用易于安装的N-烯丙基磺酰基部分作为N-自由基前体，可以实现C-H键的功能化。原位生成的N自由基参与分子内1,5-氢原子转移，生成易位的C基团，随后将其捕获在各种砜试剂中，以提供相应的CHH官能化酰胺。该方法的通用性由成功的远程C-N记录3，C-CL，C-BR，C-SCF 3，C-SPh上，和C-C键的形成。未活化的叔和仲CH键以及活化的CH主键可以通过此方法轻松地进行功能化。
