operationally simple strategy features a unified access to functionally diverse α-arylated carboxylic acids, esters, and primary, secondary, and tertiary amides through backbone assembly from simple starting materials enabled by consecutive C–F bond functionalization at room temperature. Preliminary mechanistic investigations reveal that the reaction operates through a radical-triggered three-step cascade
α-芳基化羧酸、酯和酰胺是生物活性分子中广泛存在的基序,也是化学合成中的重要组成部分。因此,非常需要直接和快速地访问这些结构。在这里,我们报告了在烷基三氟硼酸盐、水和氮/氧亲核试剂存在下对 α-三氟甲基烯烃进行彻底脱氟的有机光催化多组分合成 α-芳基化羧酸、酯和酰胺。这种操作简单的策略的特点是通过在室温下连续 C-F 键功能化实现的简单起始材料的骨架组装,统一访问功能多样的 α-芳基化羧酸、酯以及伯、仲和叔酰胺。
