A simple and efficient protocol for palladium-catalyzed C8–H alkoxycarbonylation of 1-naphthylamine derivatives with alkyl chloroformates has been developed, exhibiting broad functional group tolerance, high regioselectivity, and oxidant-free conditions. Furthermore, the reaction features its ease of further functionalization and transformation. For example, the concise synthesis of one BET bromodomain
已经开发了一种简单有效的方案,用于钯催化1-萘胺衍生物与烷基氯甲酸酯的C8–H烷氧基羰基化,具有宽泛的官能团耐受性,高区域选择性和无氧化剂条件。此外,该反应具有易于进一步官能化和转化的特征。例如,从获得的烷氧羰基化产物进行多步转化后,通过苯并[ cd ]吲哚-2(1 H)-1完成了一种BET溴结构域抑制剂的简明合成。另外,对照实验表明,该反应可能涉及自由基过程,而C–H键断裂可能不参与速率确定步骤。
