Pyrazoles and isoxazoles with cyclopropanated side‐chain were prepared by cyclization of cyclopropanated 1,3,5‐tricarbonyl compounds with hydrazine and hydroxylamine, respectively. The regioselectivity is influenced by the reaction conditions.
具有环丙烷化侧链的吡唑和异恶唑分别通过将环丙烷化的1,3,5-三羰基化合物与肼和羟胺环化而制得。区域选择性受反应条件的影响。
