Abstract
The development of an asymmetric protocol for the reductive alkynylation of amides to access important alfa-chiral tertiary propargylic amines is reported using tandem Ir-catalyzed hydrosilylation/enantioselective Cu-catalyzed alkynylation. The reaction utilizes a Cu/PyBox catalyst system in the alkynylation step to achieve asymmetry and affords excellent yields with moderate to good levels of enantiocontrol while employing low Ir-catalyst loadings (0.5 mol %).
