Abstract The asymmetric ortho lithiation of benzaldehyde chromiumtricarbonyl complex is performed by in situ temporary protection of the aldehyde functionality with a chiral amide and BuLi as metallating agent. Reaction with an electrophile followed by acidic hydrolysis leads to the enantiomerically enriched ortho substituted benzaldehyde chromiumtricarbonyl complex.
