1,3-Dipolar cycloaddition reactions of polymer-supported nitrones with alkenes proceeded smoothly in the presence of a catalytic amount of a lanthanide triflate to afford the corresponding 2-isoxazolines in high yields. Diverse 2-isoxazoline derivatives were prepared based on these solid-phase reactions.
在催化量的三氟甲烷磺酸镧系元素的存在下,聚合物负载的硝基化合物与烯烃的1,3-偶极环加成反应平稳进行,从而以高收率提供了相应的2-异恶唑啉。基于这些固相反应制备了不同的2-异恶唑啉衍生物。
