Christoph Heinz et al.
Journal of the American Chemical Society, 140(6), 2292-2300 (2018-01-18)
This report describes a three-component, Ni-catalyzed reductive coupling that enables the convergent synthesis of tertiary benzhydryl amines, which are challenging to access by traditional reductive amination methodologies. The reaction makes use of iminium ions generated in situ from the condensation
