  extracellular loop (LEL) of the CD81‐receptor (crystal structure: PDB‐ID: 1G8Q). After benzyl salicylate had been experimentally validated to be a moderate inhibitor of the CD81‐LEL–HCV‐E2 interaction, further optimization was performed and heterocyclic‐substituted benzyl salicylate derivatives were synthesized. The compounds were tested for their ability to inhibit the interaction of a fluorescence‐labeled

  Aryl carboxylic acids are among the most abundant substrates in chemical synthesis and represent a perfect example of a traceless directing group that is central to many processes in the preparation of pharmaceuticals, natural products and polymers. Herein, we describe a highly selective method for the direct step-down reduction of carboxylic acids to arenes, proceeding via well-defined Pd(0)/(II)

  芳基羧酸是化学合成中最丰富的底物之一，是无痕导向基团的完美例子，它是药物、天然产物和聚合物制备过程中许多过程的核心。在此，我们描述了一种通过明确定义的 Pd(0)/( II) 催化循环。该方法显示出非常广泛的底物范围，能够通过氧化还原中性机制将经典的酰基还原导向选择性脱羰。该反应的实用性在药物和天然产物的直接去功能化中得到了强调，并在与原脱羧正交的温和、氧化还原中性条件下使用可去除羧酸的一系列无痕过程中得到了进一步强调。进行了广泛的 DFT 计算以证明可逆氧化加成的优选选择性，并表明通用的氢原子转移 (HAT) 途径是可操作的。
