  An Alternative Method for the Synthesis of γ-Lactones by Using Cesium Fluoride-Celite/Acetonitrile Combination

  摘要：

  A variety of 2-(1-bromoalkyl) benzoic acids 4 undergo intramolecular nucleophilic substitution reaction when treated with a CsF-Celite as solid base in acetonitrile under reflux condition to give the corresponding cyclized phthalides in moderate to very good yield. These 2-(1-bromoalkyl) benzoic acids 4 are formed by the alpha-bromination of 2-alkylbenzoic acids 3 using N-bromosuccinimide and a catalytic amount of alpha,alpha'-azoisobutyronitrile in carbon tetrachloride under reflux.

  A functionalization of benzylic C(sp3)–H bonds was established through a mild metal-free intramolecular lactonization protocol in the presence of DDQ/tert-butyl nitrite as photocatalysts, allowing practical and low-cost access to a series of phthalide products in moderate to excellent yields. Compared with many existing methodologies, this visible-light-driven process exhibits an excellent substrate scope and fascinating features, including the formation of water as the sole byproduct, an abundant and green energy source, commercially available catalysts, and room-temperature reaction. Finally, detailed mechanistic investigations clearly revealed the role of the photocatalysts and molecular oxygen.

  摘要 在以 DDQ/亚硝酸叔丁酯为光催化剂的条件下，通过温和的无金属分子内内酯化协议建立了苄基 C(sp3)-H键的官能化，从而以中等至极好的产率获得了一系列邻苯二甲酸酯产品，而且成本低廉，非常实用。与许多现有方法相比，这种可见光驱动的工艺具有极佳的底物范围和引人入胜的特点，包括以水的形成为唯一副产物、丰富的绿色能源、市场上可买到的催化剂以及室温反应。最后，详细的机理研究清楚地揭示了光催化剂和分子氧的作用。

  The γ C–H amination of carboxylic acid presents a promising and sustainable strategy for synthesizing high-value pharmaceutical chemicals. Radical reaction pathways initiated by aroyloxy radical-involved hydrogen atom transfer (HAT) provide diverse but challenging opportunities for remote C–H functionalization. In this report, the first example of intramolecular γ C–H amination of carboxylic acids

  羧酸的γC-H胺化为合成高价值医药化学品提供了一种有前途且可持续的策略。由芳酰氧基参与的氢原子转移（HAT）引发的自由基反应途径为远程C-H官能化提供了多样化但具有挑战性的机会。在本报告中，实现了使用市售肟助剂对羧酸进行分子内 γ C-H 胺化的第一个例子。这种创新方法采用自由基中继分子伴侣，通过1,5-HAT/自由基交叉偶联促进选择性 C-H 官能化，并实现氨在羧酸的 γ 碳上的净结合。此外，该方案还可以回收副产物二苯甲酮，并且产物分离和副产物回收均无需硅胶。该反应具有高化学和区域选择性，在温和的反应条件下进行，具有广泛的底物范围，表现出良好的官能团兼容性，并且易于扩展。
