A new type of sugar-fused isoxazoline N-oxides was synthesized from 2-nitroglycals via [1+4] condensation with bromomalonate under the action of DBU. In addition, 1,3-dipolar cycloaddition of these isoxazoline N-oxides with alkene and alkyne dipolarophiles were also investigated.
以2-硝基甘醇与溴丙二酸在DBU作用下[1+4]缩合合成了一种新型的糖稠合异恶唑啉N-氧化物。此外,还研究了这些异恶唑啉 N-氧化物与烯烃和炔烃偶极亲和体的 1,3-偶极环加成反应。
