quinazolin-4(3H)-ones has been developed using immobilized arylguanidines. The latter were obtained by treating the amino group of polymer-linked anthranilamide with isothiocyanates followed by coupling with secondary amines in the presence of DIC. Finally a cyclative cleavage strategy was applied to give the desired compounds in high yields and purities.
使用固定化的芳基胍开发了一种通用方法,用于固相合成差异取代的喹唑啉-4(3 H)-one。后者是通过用异硫氰酸酯处理聚合物连接的邻氨基苯甲酰胺的氨基,然后在DIC存在下与仲胺偶联而获得的。最终,采用了循环裂解策略,以高收率和纯度获得所需化合物。
