A mild and rapid procedure to the synthesis of 2-substituted pyrimidines was developed via sequential functionalization of easily available Biginelli 3,4-dihydropyrimidine-2(1H)-ones via oxidation, esterification, followed by cross-coupling reaction of pyrimidin-2-yl sulfonates with N, S, and O nucleophiles in PEG-400 as a green reaction medium at room temperature.
通过氧化、酯化以及嘧啶-2-的交叉偶联反应对容易获得的 Biginelli 3,4-二氢嘧啶-2(1H)-酮进行顺序功能化,开发了一种温和且快速的合成 2-取代嘧啶的方法在室温下作为绿色反应介质,在 PEG-400 中使用 N、S 和 O 亲核试剂制备基磺酸盐。
