the use of urea as a nitrogen source, elemental sulfur as a promoter, DABCO as a base, and DMSO as a solvent. Functionalities such as chloro, fluoro, trifluoromethyl, thienyl, and indolyl groups were all compatible with the reaction conditions. Because our method uses stable simple substrates to obtain the N,N-heterocycles in the absence of transition metals, it offers a potential pathway for preparing
我们报告了一种通过 2-硝基苯甲醇与芳基乙酸缩合合成取代喹唑啉的新方法。转化需要使用尿素作为氮源,元素硫作为促进剂,DABCO 作为碱,DMSO 作为溶剂。氯、氟、三氟甲基、噻吩基和吲哚基等官能团均与反应条件相容。由于我们的方法使用稳定的简单底物在没有过渡金属的情况下获得 N,N-杂环,因此它为在温和条件下制备复杂结构提供了潜在途径。
