efficient and halogen-free catalytic methodology for the synthesis of β-aminoalcoholsfrom aromatic amines and biomass-derived carbohydrates is demonstrated for the first time. The activation of C5/C6 sugars by a ruthenium catalyst selectively generates the C2 alkylating reagent glycolaldehyde. The transformation involves metal-catalyzed hydrogenborrowing for the reduction of the imine intermediate. A series
