联芳基类化合物是非常重要的有机结构, 并且它们广泛存在于药物、功能材料以及天然产物之中. 通过新颖而又独特的反应性, 脱羰反应绕过了脱羧反应, 在芳(杂环)羧酸必须有特定取代基的限制, 逐渐成为羧酸衍生物向联芳基类化合物转化合成中难以忽视的一类方法. 发展了一例铑催化羧酸原位生成酰氟的脱羰Suzuki-Miyaura偶联反应, 该方法对芳基羧酸和硼酸有很好的官能团兼容性, 甚至可以用来合成传统方法难以获得的天然产物和修饰药物.

The biaryl frameworks are momentous organic backbones that are commonly occurred in pharmaceutical, functional materials and natural products. By virtue of the distinctive reactivity through state-of-the-art process, decarbonylative couplings, which have bypassed the restriction to specifically substituted (hetero)aryl carboxylic acids of decarboxylative couplings, gradually become unneglected methods in the conversion of carboxylic acid derivatives. Herein, a rhodium-catalyzed decarbonylative Suzuki-Miyaura cross-coupling via in-situ generation strategy of acyl fluorides from carboxylic acids was developed. This protocol shows eminent functional group tolerance with arrays of combinations between carboxylic acid and boronic acid. Furthermore, the reaction offers a new access to those conventionally unattainable biaryl motifs, including natural product and modified drugs.

Key words: rhodium catalysis, decarbonylative cross-coupling, in-situ generation, acyl fluorides
