The present invention relates to a process for the regioselective synthesis of compounds of the formula (I), (I) wherein D, J and W have the meanings indicated in the claims. The present invention provides an efficient and general palladium-catalyzed coupling process of heteroaryl tosylates with terminal alkynes to a wide variety of substituted, multifunctional heteroaryl-1 -alkynes of the formula I useful for the production of pharmaceuticals, diagnostic agents, liquid crystals, polymers, herbicides, fungicidals, nematicidals, parasiticides, insecticides, acaricides and arthropodicides.
本发明涉及一种用于选择性合成具有式(I)的化合物的方法,其中式(I)中的D、J和W具有索要权利中指示的含义。本发明提供了一种高效且通用的钯催化偶联过程,将杂环芳基对甲苯磺酸酯与末端炔烃耦合,形成广泛替代的、多功能的杂环芳基-1-炔烃,该化合物对于制药、诊断试剂、液晶、聚合物、除草剂、杀菌剂、线虫杀剂、杀虫剂、螨虫杀剂和节肢动物杀剂的生产非常有用。
