A synthesis of S,S-DICHED (dicyclohexylethane-1,2-diol), a C 2-symmetrical chiral director for Matteson homologations, is described. It relies on the insertion of lithiated S-2-cyclohexyloxirane into cyclohexylboronic acid pinacol ester and proceeds in three linear steps from readily available starting materials. No step requires chromatography or any specialized equipment.
