摘要：

(S,S)-bis-p-Tolylsulfinylmethane, 1, and (S,S)-2.2-bis-(p-Tolylsulfinyl)propane, 2, were converted into their Fe(III) complexes I and II, respectively. These complexes were shown to be good chiral catalysts of the Diels-Alder reaction between 3-acryloyl-1,3-oxazolidin-2-one, 4, and cyclopentadiene. The good enantioselection observed (36 and 56%, respectively) can be explained by the model depicted in Figure 2.
