A simple and efficient method for the base-mediated synthesis of unsymmetrical 1,3,5-triazin-2-amines has been developed. The protocol uses readily available imidates, guanidines, and amides or aldehydes as the starting materials, cesium carbonate as the base, no catalyst or additive is required, and the three-component reaction provides diverse 1,3,5-triazin-2-amines in moderate to good yields with
已开发出一种简单有效的方法,用于碱介导的不对称1,3,5-triazin-2-amines的合成。该方案使用容易获得的酰亚胺化物,胍和酰胺或醛作为起始原料,碳酸铯作为碱,不需要催化剂或添加剂,三组分反应可提供多种1,3,5-三嗪-2-胺具有中等到良好的产量,对宽泛的官能团具有耐受性。
