  在水介质中用亚硫酸钠对苯酚和杂芳族化合物进行还原脱卤和脱卤磺化

  摘要：

  质子互变异构被用作在水介质中使用亚硫酸钠作为唯一试剂的（杂）芳基溴化物和碘化物的还原性脱卤化或（杂）芳基氯和氟化物的脱卤化磺化的工具。该方案不需要金属或相转移催化剂，避免使用有机溶剂作为反应介质。此方法特别适用于容易互变异构的底物（例如2-或4-卤代氨基酚和4-卤代间苯二酚），在温和的反应条件下（≤60°C）会进行脱卤或磺化。由于亚硫酸钠是一种廉价，安全且对环境无害的试剂，因此该方法至少具有三个潜在应用：（i）使用亚硫酸钠作为还原剂对卤素作为保护基进行脱保护；（ii）在温和的反应条件下磺化芳族卤化物，避免使用危险和腐蚀性的试剂/溶剂；（iii）将有毒的卤代芳族化合物转化为危害较小的化合物。

  Effect of Alteration of the Heterocyclic Nucleus of Indolactam V on Its Isoform Selectivity for PKC. Palladium-Catalyzed Route to Benzofuran Analogs of ILV

  摘要：

  The discovery of isoform-selective modulators of protein kinase C (PKC) appears worthwhile in further defining the roles of the individual PKC isoforms in cell type-specific processes. In comparison with the phorbol esters, little information is available regarding the isoform selectivity of the teleocidin family. Blumberg has reported recently that 7-n-octylindolactam V exhibits little if any selectivity for the isoforms tested. In order to probe the possibility of developing isotype-selective agents based on the indolactam V (ILV) structure, we sought to explore replacement of the indole nucleus by a benzofuran ring. Herein we describe a novel palladium-catalyzed route to four benzofuran analogues 11a-d of ILV together with details of their isoform selectivity. Of considerable interest is the unexpected finding that this subtle N to O structural change leads to a compound (11b) that is modestly more like 12,13-dibutyrate phorbol and less like n-octyl-ILV in its pattern of activity. Moreover, the effect of introducing an additional stereocenter at C-14 into these benzofurans was explored, and a clear preference for R-stereochemistry at the C-14 center of the teleocidin family was found, thus providing additional verification of previously published structural correlations between the families of PKC activators. Overall, the present findings provide an important new direction in the quest for isoform-selective activators of PKC.

  The enantioselective syntheses of axially chiral heterobiaryls were accomplished through the aromatic electrophilic halogenation of 3‐(quinolin‐8‐yl)phenols with bifunctional organocatalysts that control the molecular conformations during successive halogenations. Axially chiral quinoline derivatives, which have rarely been synthesized in an enantioselective catalytic manner, were afforded in moderate‐to‐good

  轴向手性杂二芳基的对映选择性合成是通过3-（喹啉-8-基）苯酚的芳香亲电卤化与双功能有机催化剂来控制的，该双功能有机催化剂在连续的卤化过程中控制分子的构象。轴向手性喹啉衍生物很少以对映选择性催化方式合成，通过溴化反应可得到中等至良好的对映选择性，类似的方案也可实现对映选择性碘化。此外，这种催化反应允许通过使用单邻位取代的底物进行对映选择性控制，从而实现了高对映选择性下带有两个不同卤素基团的8-芳基喹啉衍生物的不对称合成。
