The authors demonstrated a Hf(OTf)4-Me3SiCl-system-catalyzed aminomethylation of an aromatic compound, such as a heterocycle or an electron-rich arene, with several new types of N,O-acetals having both a cyano group and a cyclic amino moiety. This method permits the facile synthesis of artificial aromatic amino acid precursors.
作者展示了一种由Hf(OTf)4-Me3SiCl系统催化下进行的芳香化合物(如杂环化合物或富电子芳香烃)的氨基甲基化反应,该反应可生成几种新型含氰基和环氨基的N,O-缩醛。这种方法能够方便地合成人工芳香氨基酸的前体。
