selective generation of the desired product can be challenging. Herein, we report that a highly chemo-, regio- and enantioselective reductive hydrocarbonylation of alkenes has been achieved using a chloroformate ester as a source of CO. A wide range of structurally diverse α-hydroxyketones, privileged structural elements in bioactive molecules and useful building blocks, were obtained from such reactions
NiH 催化的多组分烯烃还原加氢官能化是一种有吸引力但探索不足的快速增加分子复杂性的方法。在此过程中,选择性生成所需产品可能具有挑战性。在此,我们报道了使用氯甲酸酯作为 CO 来源实现了烯烃的高度化学选择性、区域选择性和对映选择性还原烃基化。多种结构多样的 α-羟基酮、生物活性分子中的特殊结构元素和有用的构建块,是从这种具有高对映体纯度的反应中获得的。

functionalized α-stereocenter, including enantioenriched chiral α-aryl ketones and α-amino ketones. It useschiral bisoxazoline as a ligand, silane as a reductant, chloroformate as a safe CO source, and a racemic secondary benzyl chloride or an N-hydroxyphthalimide (NHP) ester of a protected α-amino acid as the alkylation reagent. The benign nature of this process renders this method suitable for late-stage functionalization
已经开发出一种镍催化、多组分区域选择性和对映选择性偶联,通过顺序加氢甲酰化和羰基化从容易获得的起始材料中进行。这种模块化的多组分加氢官能化策略能够对各种未活化的烯烃进行直接的还原烃基化,以产生各种带有功能化 α-立体中心的不对称二烷基酮,包括对映体富集的手性 α-芳基酮和 α-氨基酮。它使用手性双恶唑啉作为配体,硅烷作为还原剂,氯甲酸酯作为安全的 CO 源,外消旋仲苄基氯或N受保护的 α-氨基酸的 -羟基邻苯二甲酰亚胺 (NHP) 酯作为烷基化试剂。该过程的良性性质使该方法适用于复杂分子的后期功能化。
