The nano magnetic Fe₃O₄ (NM−Fe₃O₄) was applied for the synthesis of benzoxazoles via a C(aryl)−OH functionalization of catechol derivatives and amines in ethanol at room temperature. In the next step, amino acids have been applied as nontoxic and cheap alternatives for amines. The obtained products were similar with the regular amines case. This is the first report about the application of amino acids as alternatives for primary amines in organic synthesis. Furthermore, the presented method was successfully applied toward the synthesis of desired products in large scales.

氨基酸：通过邻苯二酚的氧化功能合成苯恶唑的胺类的无毒廉价替代品

纳米磁性的Fe ₃ ö ₄（NM-的Fe ₃ ö ₄）施加用于苯并恶唑的合成通过一个C（芳基）-OH在室温下在乙醇儿茶酚衍生物和胺的官能化。在下一步中，氨基酸已被用作胺的无毒且廉价的替代品。所得产物与常规胺的情况相似。这是关于氨基酸在有机合成中作为伯胺替代品的应用的第一份报告。此外，所提出的方法已成功地用于大规模合成所需产物。
