Enantioselective reduction of C=N double bond by chromium(II) complexes of natural amino acids

Enantioselective reduction of C=N double bond by chromium(II) complexes of natural amino acids

Asymmetric reduction of oximes was performed by chromium(II) complexes of natural amino acids in aqueous phase or in H2O/DMF (1:1) solvent. Medium‐to‐quantitative chemoselectivity (54% to >95%) and low‐to‐medium enantioselectivity (5–50% ee) were found. © 2005 Wiley‐Liss, Inc. Chirality 17:511–51...
