The first palladium-catalyzed direct C5-arylation of azole-4-carboxylates with simple unactivated arenes through double CâH bond cleavage is realized. This protocol provided a straightforward access to diverse 5-arylsubstituted azole-4-carboxylic derivatives with good functional group tolerance.
首次实现了通过双C–H键断裂的铂催化直接C5-芳基化反应,将简单的未活化芳烃与azole-4-羧酸酯进行反应。该协议提供了一种简便的方法,获得了多种5-芳基取代的azole-4-羧酸衍生物,并具有良好的功能团耐受性。
