3-diol derivatives. Notably, this transformation is utilized to synthesize a range of mono- and 1,2-disubstituted alkylcyclopropanes, including those derived from terpenes, steroids, and aldol products. Additionally, enantioenriched cyclopropanes are synthesized from the products of proline-catalyzed and Evans aldol reactions. A procedure for direct transformation of 1,3-diols to cyclopropanes is also
两个 Csp3-X 键的交叉亲电偶联反应仍然具有挑战性。在此,我们报告了分子内镍催化的 1,3-二醇衍生物的交叉亲电偶联反应。值得注意的是,这种转化用于合成一系列单和 1,2-二取代的烷基环丙烷,包括衍生自萜烯、类固醇和醛醇产品的那些。此外,对映体富集的环丙烷是由脯氨酸催化和埃文斯羟醛反应的产物合成的。还描述了将 1,3-二醇直接转化为环丙烷的过程。计算和实验数据与镍催化机制一致,该机制始于二级中心的立体氧化加成。
