Reductive aminases (RedAms) catalyze the asymmetric reductive amination of ketones with primary amines to give secondary amine products. RedAms have great potential for the synthesis of bioactive chiral amines; however, insights into their mechanism are currently limited. Comparative studies on reductive amination of cyclohexanone with allylamine in the presence of RedAms, imine reductases (IREDs), or NaBH3CN support the distinctive activity of RedAms in catalyzing both imine formation and reduction in the reaction. Structures of AtRedAm from Aspergillus terreus, in complex with NADPH and ketone and amine substrates, along with kinetic analysis of active-site mutants, reveal modes of substrate binding, the basis for the specificity of RedAms for reduction of imines over ketones, and the importance of domain flexibility in bringing the reactive participants together for the reaction. This information is used to propose a mechanism for their action and also to expand the substrate specificity of RedAms using protein engineering.

A variety of secondary amines were obtained in high isolated yields in the reductive amination of aldehydes and ketones by using lithium amidoborane as reducing agent. Compared to ammonia borane, lithium amidoborane has higher reducibility, and thus, exhibits faster reaction rate.

N-alkyl(cycloalkyl)benzylamines, p-fluorobenzylamines, (1-phenylethyl) amines, [1-(p-fluorophenyl)ethyl]amines were synthesized by hydroamination of aldehydes and ketones with oximes.
