• The preparation of 3-substituted-1,5-dibromopentanes as precursors to heteracyclohexanes
  作者：Bryan Ringstrand、Martin Oltmanns、Jeffrey A Batt、Aleksandra Jankowiak、Richard P Denicola、Piotr Kaszynski

  日期：——

  The methodology to prepare 3-substituted 1,5-dibromopentanes I and their immediate precursors, which include 3-substituted 1,5-pentanediols VII or 4-substituted tetrahydropyrans VIII, is surveyed. Such dibromides I are important intermediates in the preparation of liquid crystalline derivatives containing 6-membered heterocyclic rings. Four dibromides 1a-1d containing simple alkyl and more complex

  研究了制备 3-取代的 1,5-二溴戊烷 I 及其直接前体（包括 3-取代的 1,5-戊二醇 VII 或 4-取代的四氢吡喃 VIII）的方法。这种二溴化物I是制备含有6元杂环的液晶衍生物的重要中间体。制备了四种二溴化物 1a-1d，在 3 位含有简单的烷基和更复杂的片段。3-丙基-和3-戊基-戊烷-1,5-二醇（2a，b）从戊二酸或丙二酸二酯开始制备，而四氢吡喃3c和3d从四氢-4H-吡喃-4-酮获得。讨论了每条路线的优缺点。二溴化物 1c 和 1d 用于制备锍两性离子 11c 和 11d。

  the other hand, thermolysis of 1-indanyltriphenylphosphonium bromide gave indene and triphenylphosphonium bromide. From deuterium and 13 C-labeled experiments, the interconversion of primary and secondary cation intermediates was suggested. No neighboring phenyl group (phenonium cation intermediate) interaction was observed.

  Here, we describe highly efficient intramolecular hydroarylations mediated by Re2O7/HReO4. Styrene derivatives of different electronic properties have been activated to effect a challenging intramolecular hydroarylation for the facile access to various substituted 1-aryltetralin structures. This method is characterized by mild reaction conditions, broad substrate scope, high chemical yields, and 100%

• Design, synthesis and in vitro evaluation of novel chroman-4-one, chroman, and 2H-chromene derivatives as human rhinovirus capsid-binding inhibitors

  日期：2011.12

  As part of an effort to generate broad-spectrum inhibitors of rhinovirus replication, novel series of (E)-3-[(E)-3-phenylallylidene]chroman-4-ones 1a-e, (E)-3-(3-phenylprop-2-yn-1-ylidene)chroman-4-ones 2a and 2b, (Z)-3-[(E)-3-phenylallylidene]chromans 3a-e, and (E)-3-(3-phenylprop-1-en-1-yl)-2H-chromenes 4a-d were designed and synthesized. All the compounds were tested in vitro for their efficacy against infection by human rhinovirus (HRV) 1B and 14, two representative serotypes for rhinovirus group B and A, respectively. Most of the analogues were found to be potent and selective inhibitors of both HRVs, although HRV 1B was generally more susceptible than HRV 14. Mechanism of action studies of (E)-6-chloro-3-(3-phenylprop-1-en-1-yl)-2H-chromene 4b, the most potent compound on HRV 1B infection, suggested that 4b behaves as a capsid-binder probably acting at the uncoating level.
