variety of unsymmetrical trisubstituted 1,3,5-triazines was developed. This protocol applied in situ formed acyl isocyanate from amide to react with amidine, introducing two substituents to the 1,3,5-triazinone ring with a low production cost and a simple workup procedure. The scalability of this method was demonstrated by translating a small-scale procedure to a multi-kilogram-scale synthesis. Chlorination
开发了一种可扩展的合成策略来生产多种不对称的三取代 1,3,5-三嗪。该方案应用由酰胺原位形成的酰基异氰酸酯与脒反应,以较低的生产成本和简单的后处理程序将两个取代基引入 1,3,5-三嗪酮环。该方法的可扩展性通过将小规模程序转化为数公斤规模的合成来证明。氯化和与各种亲核试剂的进一步偶联反应可以提供带有不同官能团的不对称三取代 1,3,5-三嗪。
