Introduction of the acetylene group on the 1,3,5-triazine scaffold was studied under various conditions. We describe here a new method to functionalize a triazine ring using Sonogashira coupling between 2-benzylsulfanyl-4,6-dichloro-1,3,5-triazine and trimethylsilylacetylene to give the corresponding 2-benzylsulfanyl-4-chloro-6-(trimethylsilyl)ethynyl-1,3,5-triazine. The latter was then used to obtain
在各种条件下研究了在1,3,5-三嗪支架上乙炔基的引入。我们在这里描述了一种新的方法来使用2-苄基硫烷基-4,6-二氯-1,3,5-三嗪和三甲基甲硅烷基乙炔之间的Sonogashira偶联功能化三嗪环,以给出相应的2-苄基硫烷基-4-氯-6-(三甲基甲硅烷基)乙炔基1,3,5-三嗪。然后将后者用于获得磷酸单-4- [4-(4-氨基-6-苄基硫烷基-1,3,5-三嗪-2-基)-1,2,3-三唑-1-基通过点击化学,通过Huisgen 1,3-偶极环加成反应得到]-苯基}酯。
