A readily available chiral bisoxazolidine catalyzes the asymmetric Reformatsky reaction between ethyl iodoacetate and aromatic aldehydes to yield 3-hydroxy-3-(4-aryl)propanoates in high yields and good enantioselectivities in the presence of dimethylzinc and air at room temperature within 1 h. In contrast to aromatic substrates, relatively low ee's are obtained with aliphatic aldehydes.
