and eco-friendly method for the synthesis of o-nitroarylamine from o-nitroaryl sulfonic acid via ipso nucleophilic aryl substitution by amine is described. The products have been obtained with good yields at room temperature without the assistance of any metal, activating agent, or toxic oxidant. This method is useful for racemization-free synthesis of N-aryl amino acid esters.
描述了一种温和,有效和环保的方法,该方法用于通过邻氨基芳基的ipso亲核芳基取代反应,由邻硝基芳基磺酸合成邻硝基芳基胺。无需任何金属,活化剂或有毒氧化剂的帮助,即可在室温下以高收率获得产品。该方法可用于无消旋地合成N-芳基氨基酸酯。
