Simultaneous double 1,3‐dipolar cycloaddition reactions of glyoxal‐derived bisnitrones have been described in water. Significant rate acceleration and improved yields of exclusively diastereoselective and regioselective bisisoxazolidines in water have been observed at room temperature in a short reaction time compared with conventional solvents.
乙二醛衍生的双硝基酮在水中同时发生双1,3-偶极环加成反应。与常规溶剂相比,在室温下,在较短的反应时间内即可观察到在水中的非对映选择性和区域选择性联苯二恶唑烷类化合物的明显速率加速和提高的收率。
