strategy for the synthesis of substituted isocoumarin, flavone, and isoquinolinedione derivatives through a switchable C-arylation/lactonization or SNAr reaction from a wide range of soft nucleophiles and o-quinol acetates has been developed. This base-mediated protocol proceeds under transition-metal-free conditions and selectively affords various heteroarenes in 13–98% yields from readily prepared or commercially
已经开发出一种通过可切换的 C-芳基化/内酯化或 SNA Ar 反应从各种软亲核试剂和邻羟基乙酸酯合成取代异香豆素、黄酮和异喹啉二酮衍生物的一锅策略。这种碱介导的方案在无过渡金属的条件下进行,并从易于制备或市售的 1,3-二羰基和α -EWG 取代的羰基化合物中选择性地以 13-98% 的产率提供各种杂芳烃。该合成效用在潜在抗HIV 和抗 HIV 药物的合成中得到了进一步证明。-冠状病毒衍生物和COX-2抑制剂。此外,还进行了详细的实验和计算研究,以提供对反应机理的深入理解和有力支持。
