  摘要：

  角鲨烯[1,1'-（癸烷-1，10-二基）双（2-甲基-4-氨基喹啉）]是小电导Ca2（+）激活的K +通道的有效阻滞剂。已经表明，在连接这种类型的分子的两个喹啉鎓环的烷基链中的亚甲基的数目对于活性不是关键的。为了进一步研究接头的作用，已合成了癸胺盐的类似物，其中烷基链已被CH2XCH2取代，其中X是含有芳香环的刚性或半刚性基团。已经测试了该化合物对大鼠交感神经元缓慢的超极化后的阻滞作用。最有效的化合物为X =菲基，芴基，顺二苯乙烯和C6H4（CH2）nC6H4，其中n = 0-4。使用XED / COSMIC分子建模系统研究了化合物的构象偏好。尽管类似物的效力对接头（X）的构象性质有一定的依赖性，但是总体上，具有实质性结构差异的X基团是可容忍的。X似乎为两个喹啉基团提供了支持，并且不直接与通道相互作用。刚性基团X提供的喹啉鎓环之间的分子内间隔对于活性不是关键。这可能归因于杂环的残留构象迁

• Oxidative Cyclizations, the Synthesis of Aryl-Substituted C-Glycosides, and the Role of the Second Electron Transfer Step
  作者：Jake A. Smith、Kevin D. Moeller

  DOI：10.1021/ol402826z

  日期：2013.11.15

  Anodic oxidation reactions have been used to synthesize aryl- and biaryl-substituted C-glycosides. The reactions take advantage of the tendency for alcohol nucleophiles to trap nonpolar radical cations. The addition of the alcohol to the radical cation appears to be reversible, and the success of the cyclizations is dependent on the ease with which the resulting benzylic radical is oxidized.

  阳极氧化反应已用于合成芳基和联芳基取代的C-糖苷。该反应利用了醇亲核试剂捕获非极性自由基阳离子的趋势。醇加到自由基阳离子上似乎是可逆的，并且环化的成功取决于所得苄基被氧化的难易程度。

  The syntheses of the new pentahelicenes 5, 11, 17, 21, and 28 with various substituents are described. In the case of 2,13-dicyano-[5]helicene (11) optical resolution was achieved by HPLC using a column packed with gamma-cyclodextrin. However, the enantiomers racemized within a few hours. On the other hand, the enantiomers of 28 turned out to be stable after separation on triacetylcellulose using MPLC

  p-terphenyls and 11,12-dihydroindeno[2,1-a]fluorene were successfully synthesized by one-pot benzannulation of Diels–Alder reaction with 1,2-dichloroethene as an acetylene equivalent dienophile. Two chlorine atoms could be good leaving groups to easily undergo subsequent elimination reactions of Diels–Alder products at a high temperature.

  Reaction of a range of bis(ylides) with acid chlorides has been used to prepare the bis(oxoylides) 11–15. Similarly a range of simple ylides react with bis(acid chlorides) to give bis(oxoylides) 19–27 with the isomeric structure. Flash vacuum pyrolysis (FVP) of one example of the first type results in extrusion of Ph3P rather than the expected Ph3PO while six examples of the second type do extrude

  作者：Lin Guo、Chao Yang、Lewei Zheng、Wujiong Xia

  DOI：10.1039/c3ob41245h

  日期：——

  A novel and simple procedure was developed for the regioselective synthesis of α-bromo (di)ketones from electron-rich epoxides via visible light photoredox catalysis. Through optimization of solvent and light source, the reaction can be rapidly achieved under mild conditions. Moreover, the possible reaction mechanism was proposed and further supported by control experiments.
