Aroylimidazo[1,2-a][1,3,5]triazines are rapidly synthesized via a facile and mild reaction of 2-amino-triazines and 1,3-dicarbonyl compounds using NBS. The reaction occurred with good yields and excellent regioselectivity, and β-keto esters, β-keto amides, and 1,3-diones were tolerated under the optimized procedure. In addition, the successful application of this methodology for a gram-scale reaction
使用NBS通过2-氨基三嗪和1,3-二羰基化合物的轻度和温和反应可以快速合成Aroylimidazo [1,2- a ] [1,3,5]三嗪。该反应以良好的收率和优异的区域选择性进行,并且在优化的程序下耐受β-酮酯,β-酮酰胺和1,3-二酮。此外,这种方法在克级反应中的成功应用表明其具有大量合成的潜力。
