A method for enantioselective direct α-amination reaction catalyzed by a sterically "frustrated" Lewis acid/Brønsted base complex is disclosed. Cooperative functioning of the Lewis acid and Brønsted base components gives rise to in situ enolate generation from monocarbonyl compounds. Subsequent reaction with hydrogen-bond activated dialkyl azodicarboxylates delivers α-aminocarbonyl compounds in high
公开了一种由空间上“受阻”的路易斯酸/布朗斯台德碱配合物催化的对映选择性直接α-胺化反应的方法。路易斯酸和布朗斯台德碱组分的协同作用导致从单羰基化合物原位生成烯醇化物。随后与氢键活化的偶氮二羧酸二烷基酯反应以高对映体纯度提供α-氨基羰基化合物。
