4,5-Disubstituted-3(2H)-pyridazinones were initially synthesized via sodium alkoxide additions to an advanced bromide intermediate. A small parallel chemistry effort resulted in a poor success rate, and we thus increased the reactivity of the reaction partner by performing a copper-catalyzed Finkelstein reaction. Copper-catalyzed coupling of a diverse set of alcohols with the resulting iodide resulted
最初通过将醇钠加成到高级溴化物中间体中来合成4,5-二取代-3(2 H)-哒嗪酮。少量的平行化学反应会导致成功率降低,因此我们通过进行铜催化的Finkelstein反应来提高反应伙伴的反应性。铜催化的各种醇与生成的碘化物的偶联导致更成功的努力。还描述了该系列化合物的许多替代合成,并且这些方法被证明是通用的,有效的并且适合于平行合成。
