New supported β-amino alcohols as efficient catalysts for the enantioselective addition of diethylzinc to benzaldehyde under flow conditions

[GRAPHICS] Polymeric monoliths 10 containing an amino alcohol moiety derived from an industrial waste material represent one of the best ligands for the enantioselective catalytic addition of znEt(2) to benzaldehyde (99% ee), being recoverable and usable under flow conditions.
