Catalytic enantioselective routes to bifunctional C5 synthons, including those of the macrolide (S)-(−)-zearalenone have been achieved. Stereochemistry was introduced using a mixed ligand arene chromium tricarbonyl catalyst to mediate the enantioselective addition of dimethyl zinc to a functionalized aldehyde. Comparison with alternate reduction strategies is presented.
