atom-economic, practical strategy for the synthesis of tri/tetra-substituted furans through electrochemical [3 + 2] annulation between alkynes and β-keto compounds with ferrocene (Fc) as the catalyst. This protocol features the use of a graphite felt (GF) anode and a stainless steel (SST) cathode, mild conditions, and excellent tolerance with various alkynes and β-keto compounds. Additionally, the application
在本报告中,我们描述了一种原子经济、实用的策略,以二茂铁 (Fc) 作为催化剂,通过炔烃和 β-酮化合物之间的电化学 [3 + 2] 成环来合成三/四取代呋喃。该协议的特点是使用石墨毡 (GF) 阳极和不锈钢 (SST) 阴极、温和的条件以及对各种炔烃和 β-酮化合物的优异耐受性。此外,复杂结构的后期功能化和克级实验凸显了该方法的应用。
