2-环己基环氧乙烷 | Cyclohexyloxirane | 3483-39-4 | C8H14O | 126.199 |
1-环己基乙烷-1,2-二醇 | 1-cyclohexylethane-1,2-diol | 59411-58-4 | C8H16O2 | 144.214 |
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.
