Hydrazones have been employed as the starting materials in a KOH-mediated one-pot three-component cycloaddition with readily accessible nitroso compounds and olefins to construct various isoxazolidines. Compared with diazo compounds as starting materials, this methodology could afford a wider range of products in good to excellent yields and diastereoselectivities for most substrates, and hydrazones
腙已被用作 KOH 介导的一锅三组分环加成反应的起始材料,与容易获得的亚硝基化合物和烯烃以构建各种异恶唑烷。与作为起始材料的重氮化合物相比,这种方法可以提供更广泛的产品,对大多数底物具有良好到优异的产率和非对映选择性,并且腙更便宜、更容易获得且更安全。实验研究表明,选择合适的腙至关重要。
