The first kinetic resolution of hydroquinoline derivatives with α,α‐disubstitution has been achieved through asymmetric remote aminations with azodicarboxylates enabled by chiral phosphoric acid catalysis. Mechanistic studies suggest a monomeric catalyst pathway proceeding through rate‐ and enantio‐determining electrophilic attack promoted by a network of attractive non‐covalent interactions between
通过手性磷酸催化偶氮二羧酸酯的不对称远程胺化,实现了具有α,α-二取代的氢喹啉衍生物的第一动力学拆分。机理研究表明,单体催化剂途径通过确定底物和催化剂之间有吸引力的非共价相互作用网络促进速率和对映体确定亲电性进攻。新引入的肼部分的后续轻松移除和转化使这些方案成为强大的工具,可用于不对称合成具有α,α-取代基的N-杂环。
