  Phenyl β-Methoxyacrylates:  A New Antimalarial Pharmacophore

  摘要：

  Phenyl beta-methoxyacrylates, linked to an aromatic ring via an olefinic bridge, have been identified as novel, potentially inexpensive, antimalarial agents. The compounds are believed to exert their activity by inhibition of mitochondrial electron transport at the cytochrome bc(1) complex. A series of compounds have been synthesized to define structure-activity relationships affecting antimalarial activity. It was found that the beta-methoxyacrylate was required ortho to the linker and the optimal bridge was (E,E)-butadiene, Compounds in which the second aromatic ring was ortho-substituted or ortho,para-disubstituted gave optimal potency. Several compounds were identified with potency that is superior to that of chloroquine both in culture and in a murine malaria model.

  Transition-metal-catalyzed cross-coupling reactions between naturally abundant sp3-hybridized carbon centers facilitate access to diverse molecules with complex three-dimensional structures. Organometallic compounds are among one of the most powerful reagents that are broadly used in carbon–carbon bond formations. Although sp2-hybridized organometallic compounds are widely employed in cross-couplings, sp3-hybridized

  自然丰富的sp 3-杂化碳中心之间的过渡金属催化交叉偶联反应有助于获得具有复杂三维结构的各种分子。有机金属化合物是最强大的试剂之一，广泛用于碳-碳键的形成。尽管sp 2-杂化的有机金属化合物广泛用于交叉偶联，但是sp 3-杂化的有机金属偶联剂的开发较少。在这里，我们报告可见光诱导的单个镍催化的C（sp 3）–C（sp 3），C（sp 3）–C（sp 2）和C（sp 3）–C（sp）使用烷基锆茂的交叉偶联反应，该反应很容易从末端或内部未活化的烯烃通过加氢锆和链步反应就地生成。该方法温和，适用于多种底物，包括伯，仲，叔烷基，芳基，烯基，炔基卤化物和各种烯烃。机理研究表明，镍催化的自由基交叉偶联是一种新颖的途径，代表了锆锆茂的首次可见光诱导的转变。

  simple copper‐catalyzed alkyl–alkynyl cross‐coupling strategy has been developed using the reaction between alkynyl bromides and alkylzirconocenes. The alkylzirconocenes were generated in situ via regioselective addition of Schwartz's reagent (ZrCp2HCl) on to alkenes. The reaction has a broad scope, a range of functionalized bromoalkynes and alkylzirconium reagents were successfully coupled, resulting in

  Strain versus flexibility: The palladium‐catalyzed reaction of haloalkynes with norbornene derivatives leads to 7‐alkynyl norbornane products (see scheme). Key to the success of this reaction is the formation of a “bridging” palladium species, which can rearrange to result in a C‐7 functionalization. The ring‐structure‐dependent [2+2] cycloaddition of haloalkynes with cyclooctene has been achieved in
