Asymmetric α-amination of β-keto esters using a guanidine–bisurea bifunctional organocatalyst
An asymmetric α-amination of β-keto esters with azodicarboxylate in the presence of a guanidine–bisurea bifunctional organocatalyst was investigated. The α-amination products were obtained in up to 99% yield with up to 94% ee.
