“…4 The foundation for dual catalysis has been laid based on the utilization of two catalysts in one-pot, working in synchronization to enable a single synthetic transformation. In this regard, several dual catalytic systems merging metal–metal, 5 organo–organo 6 and metal–organocatalysts 7 have been devised to achieve unique molecular scaffolds with excellent levels of chemo-, regio- and stereoselectivity. Among these merged catalytic systems, the strategy involving the combination of transition metals and chiral organocatalysts has been enormously applied in the realm of asymmetric organic synthesis.…”

The development of nanostructured organocatalysts is emerging as a prominent field in materials science. To this purpose, nitrogen-doped carbon dots (CDs) have been effectively employed in enantioselective enamine organocatalysis. On the other hand, enantioselective iminium ion nano-organocatalysis is much less explored. In this Letter, the use of CDs in asymmetric iminium ion catalysis via asymmetric counteranion-directed catalysis (ACDC) is disclosed. Nonchiral CDs bearing butylenediamine residues proved to be the most effective ones, in combination with (S)-TRIP as a chiral phosphoric acid (CPA). A correlation between the features of the CDs' surfaces and their catalytic performance was shown, and the catalytic activity of the employed CDs proved to be higher than that of simple molecular amines. An extensive reaction optimization allowed the reduction of different α,β-unsatured aldehydes in good yield and ee, using a low catalyst loading.
