The synthesis of highly substituted indenes has been achieved by three different transition metal-mediated methods. The first method involves the palladium-catalyzed carboannulation of internal alkynes. The second method utilizes a two-step approach, which involves first the palladium/copper-catalyzed cross-coupling of terminal alkynes with appropriately functionalized aryl halides, followed by copper-catalyzed
通过三种不同的过渡金属介导的方法可以实现高度取代的茚的合成。第一种方法涉及内部炔烃的钯催化碳环化反应。第二种方法采用两步法,其中首先涉及末端炔烃与适当官能化的芳基卤化物的钯/铜催化交叉偶联,然后进行铜催化的分子内环化。第三种方法涉及在第二种方法的第一步中形成的芳基炔烃的分子间钯催化的芳基化。
