A novel asymmetric-axle-supported chiral N-O amide was synthesized and used in catalytic enantioselective hydrosilylation of N-aryl ketimines with HSiCl3 at room temperature instead of the typical -20°C. High conversion yield and high enantiose

A series of axially chiral biscarboline-based sulfones were synthesized from L-tryptophane and applied for enantioselective 1,2-transfer hydrogenations of ketimines using trichlorosilane. The catalyst 4e, which had a tertiary butyl group, exhibited a good conversion and high enantioselectivities up to 96%ee in the series of reactions.
