We report herein a catalytic asymmetric dehydrogenative cross-coupling reaction between enones and tertiary amines enabled by synergistic photoredox and chiral primary amine catalysis. The reaction was proposed to proceed via the interception of iminium ion intermediate, in situ generated from photoredox oxidation, by dienamine at α-position, following by isomerization, leading to aza-Morita-Baylis-Hillman-type products with good diastereo- and enantio- selectivity.
