The direct mechanochemical amidation of esters by ball milling is described. The operationally simple procedure requires an ester, an amine, and substoichiometric KOtBu and was used to prepare a large and diverse library of 78 amide structures with modest to excellent efficiency. Heteroaromatic and heterocyclic components are specifically shown to be amenable to this mechanochemical protocol. This
描述了通过球磨对酯进行直接机械化学酰胺化。操作简单的程序需要一种酯、一种胺和亚化学计量的 KOtBu,并被用于制备一个包含 78 个酰胺结构的大型和多样化的库,效率适中至极好。杂芳族和杂环组分特别表明适合这种机械化学协议。这种直接合成平台已应用于活性药物成分 (API) 和农用化学品的合成以及活性药物的克级合成,所有这些都在没有反应溶剂的情况下进行。
