The Pummerer reaction of acetic anhydride with both alkyl aryl sulfoxides and dialkyl sulfoxides was efficiently promoted by a mesoporous aluminosilicate Al-MCM-41 to afford the corresponding α-ace...

absolute configurations at the metal centers and sulfur atoms were determined by means of X‐ray crystallography. The results indicate that the configurations of the metal centers are retained and have the function of controlling sulfoxide chirality during the oxidation process. The Δ metal‐centered configuration enantioselectively generates an R‐configuration sulfoxide, and the Λ configuration enantioselectively
