The dipolar cycloadditions of ortho-nitrophenyl alkynes with aryl nitrile oxides has been demonstrated. A range of substituents are tolerated on the alkyne. These reactions proceed with excellent levels of regioselectivity. Subsequent functionalization of the isoxazole scaffold has been demonstrated.
已证明邻硝基苯基炔烃与芳基腈氧化物的偶极环加成。炔烃上可容忍一系列取代基。这些反应以极好的区域选择性进行。已经证明了异恶唑支架的随后功能化。
