The stereoselective intramolecular nitrile oxide cycloaddition (INOC) reaction was achieved from N-formyl-β-nitroamides, which were prepared through the Michael addition of allylic formamides to nitroalkenes, and cis-pyrroroisoxazoles and trans-piperidinoisoxazoles were obtained in a stereoselective manner.
由N-甲酰基-β-硝基酰胺实现立体选择性分子内腈氧化环加成反应(INOC),该反应是通过将烯丙基甲酰胺与硝基烯烃进行迈克尔加成反应而制得的,并以立体选择性方式获得了顺式-吡咯基异恶唑和反式-哌啶基异恶唑。
