the direct formylation of benzothiazo/les and isoquinolines. The reaction features a novel iron-catalyzed Minisci-type oxidative coupling process using commercially available 1,3-dioxolane as a formylated reagent followed by acetal hydrolysis without a separation process. The reaction can be performed under exceedingly mild reaction conditions and exhibits broad functional group tolerance.
醛基是合成化学中最通用的中间体之一,并且将醛基引入杂芳烃对于分子结构的转化很重要。在这里,我们实现了苯并噻唑/莱和异喹啉的直接甲酰化。该反应具有新颖的铁催化的Minisci型氧化偶联工艺,该工艺使用可商购的1,3-二氧戊环作为甲酰化试剂,然后进行乙缩醛水解而无需分离过程。该反应可以在非常温和的反应条件下进行,并且表现出宽泛的官能团耐受性。
