assembled in situ from a chiral biaryl ligand, an amine, water, BH3⋅SMe2 , and an alcohol or phenol. The catalyst screen included 13 different ligands, 12 amines, and 47 alcohols or phenols. The optimal catalyst system (LAP 8‐5‐47) provided α‐amino amides from an aldehyde, a secondary amine, and an isonitrile with excellent asymmetric induction. The catalytically active species is proposed to be an ion
The reductivecoupling of aromatic N,N-acetals and N,O-acetal activated by chlorotrimethylsilane proceeded smoothly in the presence of zinc to give the corresponding diamines in good yields.

A novel silver-catalyzed nucleophilicsubstitution of aminals with ethyl diazoacetate producing β-amino-α-diazoesters has been developed. A series of aminals with different amino moieties and substituents were successfully incorporated in this reaction, which delivered a wide range of β-amino-α-diazocarbonyl compounds in the presence of a lower catalyst loading in 2 hours.
