approach for the synthesis of isoxazoline derivatives is reported. This protocol involves 1,3-dipolar cycloaddition between in situ generated nitrile oxides from the corresponding aldoximes using [hydroxy(tosyloxy)iodo]benzene (HTIB, Koser’s reagent) and maleimides, styrene and acrylonitrile. The described methodology is very attractive as it is operationally simple, has broad scope, and does not require
报道了一种用于合成异恶唑啉衍生物的无金属和无碱、稳健且方便的方法。该协议涉及 1,3-偶极环加成,使用 [羟基(甲苯磺酰氧基)碘] 苯(HTIB,Koser 试剂)和马来酰亚胺、苯乙烯和丙烯腈从相应的醛肟原位生成的腈氧化物之间。所描述的方法非常有吸引力,因为它操作简单,范围广泛,并且不需要任何碱、金属或其他添加剂。
