This review article discusses historical and contemporary research studies of asymmetric allylic oxidation of olefins using homogeneous and heterogeneous copper complexes of various kinds of oxazoline-based ligands, until the end of 2021. It is revealed that this strategy is a powerful method to form a new stereogenic center bearing an oxygen substituent adjacent to an unchanged C=C bond. Enantioselectivities as well as chemical yields, and also the reactivity, are strongly dependent on the type of substrate, oxidant, the copper salt and its oxidation state, ligand structure, temperature, nature of the solvent, and additives such as phenylhydrazine and porous materials.

使用基于手性恶唑啉的配体的铜配合物对烯烃进行对映选择性烯丙基 C-H 键氧化
这篇综述文章讨论了使用各种恶唑啉基配体的均相和异相铜配合物对烯烃进行不对称烯丙基氧化的历史和当代研究,直至 2021 年底。结果表明,这种策略是形成新的一种强有力的方法。具有与未改变的 C=C 键相邻的氧取代基的立体中心。对映选择性以及化学产率以及反应性在很大程度上取决于底物的类型、氧化剂、铜盐及其氧化态、配体结构、温度、溶剂的性质以及添加剂(例如苯肼和多孔材料)。
