3-(methylsulfonyl)-1,2,4 triazine was also optimized. The reactivity of 3-(methylsulfonyl)-1,2,4-triazine towards alkyl and aryl thiols, primary and secondary alkylamines, phenols, and alcohols was explored, and the reactions were optimized to maximize the isolation of the corresponding 3-substituted 1,2,4-triazine. Good yields were obtained for the products of the reactions with all of the aforementioned nucleophiles
在我们尝试合成 3-(烷
硫基)-和 3-(烷氧基)-
1,2,4-三嗪时,在 5-或 6-位没有取代基,合成它们预期的前体 3-(甲基磺酰基)-1, 2,4 三嗪也进行了优化。探索了
3-(甲基磺酰基)-1,2,4-三嗪对烷基和芳基
硫醇、伯和仲烷基胺、
酚和醇的反应性,并对反应进行了优化,以最大限度地分离相应的 3-取代 1 ,2,4-三嗪。通过使用碱
金属
碳酸盐,与除醇之外的所有上述亲核试剂的反应产物获得了良好的产率。通过使用合适的醇
