The synthesis of regioisomeric spiroisoxazolines was achieved through an intramolecular cyclization/methylation reaction of a functionalized 5,5-disubstituted isoxazoline in one reaction vessel. The 5,5-isoxazoline was constructed through a 1,3-dipolar cycloaddition reaction of an aromatic nitrile oxide and a geminal disubstituted alkene.
通过在一个反应容器中对官能化的5,5-二取代异噁唑啉进行分子内环化/甲基化反应,实现了区域异构体螺环异噁唑啉的合成。5,5-异噁唑啉是通过芳香族腈和二取代烯烃的1,3-二极性环加成反应构建的。
