  Benzophenone dicarboxylic acid antagonists of leukotriene B4. 2. Structure-activity relationships of the lipophilic side chain

  摘要：

  A series of lipophilic benzophenone dicarboxylic acid derivatives were found to inhibit the binding of the potent chemotaxin leukotriene B4 (LTB4) to its receptor on intact human neutrophils. Activity at the LTB4 receptor was determined by using a [3H]LTB4-binding assay. The structure-activity relationship for the lipophilic side chain was systematically investigated. Compounds with n-alkyl side chains of varying lengths were prepared and tested. Best inhibition of [3H]LTB4 binding was observed with the n-decyl derivative. Analogues with alkyl chains terminated with an aromatic ring showed improved activity. The 6-phenylhexyl side chain was optimal. Substitution on the terminal aromatic ring was also evaluated. Methoxyl, methylsulfinyl, and methyl substituents greatly enhanced the activity of the compound. For a given substituent, the para isomer had the best activity. Thus the nature of the lipophilic side chain can greatly influence the ability of the compounds to inhibit the binding of LTB4 to its receptor on intact human neutrophils. The most active compound from this series, 84 (LY223982), bound to the LTB4 receptor with an affinity approaching that of the agonist.

  reported. Here we report a novel reaction of diazo compounds utilizing a radical-mediated addition strategy to achieve difunctionalization of diverse alkenes. Diazo compounds are transformed to carbon radicals with a photocatalyst or an iron catalyst through PCET processes. The carbon radical selectively adds to diverse alkenes delivering new carbon radical species, then forms products through hydroalkylation

  重氮化合物与烯烃最常见的反应之一是通过金属卡宾或游离卡宾中间体发生的环丙烷化反应。烯烃与重氮化合物的替代官能化是有限的，并且还没有通过碳碳双键添加 Z-CHR2 元素（Z = H 或杂原子，CHR2 源自 N2 = CR2）的方法报道。在这里，我们报告了一种利用自由基介导的加成策略实现多种烯烃双官能化的重氮化合物的新反应。重氮化合物在光催化剂或铁催化剂的作用下通过 PCET 过程转化为碳自由基。碳自由基选择性地添加到不同的烯烃中，提供新的碳自由基物种，然后通过硫醇辅助的氢原子转移 (HAT) 通过加氢烷基化形成产物，或通过铁催化循环形成叠氮烷基化产物。这两个过程是高度互补的，在温和的反应条件下进行，并表现出高度的官能团耐受性。此外，这两种转化都在克级规模上成功进行，并且可以使用市售试剂轻松制备各种 γ-氨基酯、γ-氨基醇和复杂的螺内酰胺。机理研究揭示了将这两个过程联系起来的合理途径，并解释

  A simple and regioselective synthesis of phenoxy esters and phenylthio esters is reported. The products are obtained by selective alkoxycarbonylation catalyzed by Pd2(dba)3, 1,4-bis(diphenylphisphino)butane (dppb), and syngas (CO/H2) in chloroform/alcohol. This methodology affords bifunctional products in good yield with excellent n-selectivity and without the need to use additives.
