Chiral supramolecular metal-organic frameworks assembled from copper complexes catalyse Henry and aza-Henry reactions of aromatic and aliphatic aldehydes and N-protected aromatic imines in high yield and good to excellent enantioselectivity. Reactions can

Highly enantioselective addition reactions between silyl ketene acetals and N-Boc aldimines are catalyzed by the thiourea-based catalyst 1c. Extraordinary scope is observed in this methodology with regard to the imine substrate, with aryl and heteroaromatic derivatives generally affording nearly quantitative yields of β-amino ester product in up to 98% enantioselectivity.
