A AuIII-catalyzed synthesis of α-halomethyl ketones from terminal alkynes was developed. This approach features excellent functional group compatibility and good yields for both aromatic and aliphatic terminal alkynes. The resulting α-halomethyl ketones were used to prepare heterocyclic indolizine structures. The plausible mechanism of the one-pot reaction is proposed.
开发了一种 AuIII 催化的从末端炔烃合成 α-卤代甲基酮的方法。这种方法对芳香族和脂肪族末端炔烃具有优异的官能团兼容性和良好的产率。所得的α-卤代甲基酮用于制备杂环茚茚结构。提出了一锅反应的合理机制。
