A high yield one-pot synthesis of β-amino alcohols from nitroarenes and 1,2-epoxides was developed, which utilizes inexpensive iron dust as a reducing agent and NH4Cl as the only additive in a 50% (v/v) ethanol solution. This new efficient synthetic approach tolerates a wide range of functionalities. The mild reaction conditions (e.g., 60 °C), together with the use of low cost and readily available
开发了一种由硝基芳烃和1,2-环氧化合物高产率单锅合成β-氨基醇的方法,该方法利用廉价的铁粉作为还原剂,并将NH 4 Cl用作50%(v / v)乙醇中的唯一添加剂解。这种新的有效的合成方法具有广泛的功能。温和的反应条件(例如60°C),以及使用低成本和易于获得的起始原料,使得这种合成方法成为目前β-氨基醇合成的有吸引力的替代方法。
