Aerobic oxidation has been catching more and more attention because of its atom economy and environmental friendliness. Oxidation of diols is a challenge due to various oxidative products. Thus, highly selective aerobic oxidation affording specific products is of current interest. In this work, a combination of Fe(NO3)3·9H2O/TEMPO/KCl catalysis has been identified as an efficient recipe for the aerobic
有氧氧化因其原子经济性和环境友好性而受到越来越多的关注。由于存在各种氧化产物,二醇的氧化是一个挑战。因此,提供特定产物的高选择性有氧氧化是当前关注的焦点。在这项工作中,Fe(NO 3 ) 3 · 9H 2的组合O/TEMPO/KCl 催化已被确定为在温和条件下 1,4-二醇有氧氧化生成 γ-丁内酯的有效配方。该反应对对称和不对称 1,4-二醇表现出良好的化学和区域选择性。光学活性γ-内酯也可以由光学活性1,4-二醇通过该方法制备而不侵蚀ee。此外,该方法还成功应用于合成商业药物NBP。
