Using L-phenylalaninol as chiral precursor, a series of multi-aryl substituted imidazole amino alcohol derivatives containing appended chiral functionalities were synthesized through a "four component-one pot procedure" from the condensation reaction of L-phenylalaninol, dibenzoyl (benzil), ammonium acetate and different heterocyclic aryl-aldehyde. X-ray crystal analysis confirmed that the chiral carbon retained the S configuration of L-phenylalaninol. The chiral ligands in combination with Cu(OAc)2·H2O catalyzed the enantioselective Henry reaction of nitromethane and aromatic aldehydes with moderate to high yields and excellent enantioselectivities (>99%) with S configuration. The easy availability of catalyst components, mild reaction conditions and high enantioselectivity make the system attractive for practical application.

Key words: chiral, imidazole amino alcohol, asymmetric Henry reaction
