Boric acid promoted transfer hydrogenation of substituted quinolines to synthetically versatile 1,2,3,4-tetrahydroquinolines (1,2,3,4-THQs) was described under mild reaction conditions using a Hantzsch ester as a mild organic hydrogen source. This methodology is practical and efficient, where isolated yields are excellent and reducible functional groups are well tolerated in the N-heteroarene moiety
硼酸促进了取代喹啉向合成多用途的1,2,3,4-四氢喹啉(1,2,3,4-THQs)的转移加氢反应,该反应在温和的反应条件下使用汉茨酯作为温和的有机氢源进行了描述。该方法是实用且有效的,其中分离的收率极好,并且在N-杂芳烃部分中可还原的官能团具有良好的耐受性。通过各种对照实验和NMR研究证明了反应参数和初步的机理途径。目前的工作也可以扩大规模以获得克量,并且通过将1,2,3,4-THQs转化为一系列具有生物学重要性的分子(包括抗心律不齐药物nicainoprol)来说明所开发方法的实用性。
