dehydrogenative coupling (ADC) reaction is an efficient method for synthesizing quinoline and its derivatives. In this paper, various substituted quinolines were synthesized from 2-aminobenzyl alcohols and aryl/heteroaryl/alkyl secondary alcohols in one pot via a cyclometalated iridium-catalyzed ADC reaction. This method has some advantages, such as easy availability of raw materials, mild reaction conditions
无受体脱氢偶联(ADC)反应是合成喹啉及其衍生物的有效方法。本文以2-氨基苄醇和芳基/杂芳基/烷基仲醇为原料,通过环金属化铱催化的ADC反应,在一锅中合成了多种取代的喹啉。该方法具有原料易得、反应条件温和、底物范围广、环境友好等优点,符合绿色化学原理。此外,具有低催化剂负载的克级实验提供了获得合适量的芳基/杂芳基喹诺酮类药物的潜力。此外,还对合成的喹啉的抗菌和抗真菌活性进行了体外评价,3ab、3ad和3ah对革兰氏阳性菌和化合物3ck对白色念珠菌的作用优于参考药物诺氟沙星。
