An unprecedented efficient method for the reductive amination of carbonyl derivatives with ω-amino fatty acids under hydrosilylation conditions was developed leading to the corresponding lactams. A variety of pyrrolidinones, piperidinones, 2-azepanones were prepared in up to 95 % isolated yields (29 examples).
Visible-Light-Promoted Dual Photoredox/Nickel-Catalyzed Chemoselective Reduction of Secondary and Tertiary Amides with Hydrosilanes in the Presence of an Ester
report a one-step procedure to selectively reduce secondary and tert-amides to their corresponding amine derivatives in the presence of an ester. This was achieved via the synergistic combination of a photoredox, a nickel catalytic system, and phenyl silane as a reductant in the presence of blue light-emitting diode light (455 nm) at room temperature. Further, this mild light-promoted dual metallaphotoredox
