Use of sulfated tungstate as an efficient, green and reusable catalyst for preparation of thiomorpholides via Willgerodt–Kindler reaction pathway is presented. The reaction proceeds under solvent free condition. The advantages of this method are high yields, short reaction times, ease of product isolation and recyclability of catalyst for a number of times without significant loss of activity.
本文介绍了使用硫酸钨作为一种高效,绿色且可重复使用的催化剂,通过Willgerodt-Kindler反应途径制备硫吗啡内酯的方法。反应在无溶剂条件下进行。该方法的优点是产率高,反应时间短,产物分离容易和催化剂可循环使用多次,而活性没有明显损失。
