Both diastereomers including the syn- and anti-α-alkoxy-β-hydroxy-β-methyl units are prepared from (E)- and (Z)-1-trimethylsiloxy-1-ethylthio-2-benzyloxyethene and a pyruvic acid ester, respectively, by using aluminum triflate-mediated aldol reactions. (±)-2-C-Methyl-D-erythrono-1,4-lactone and (±)-2-C-methyl-D-threono-1,4-lactone are synthesized by using these reactions.
