A complete synthesis of enantiopure trans-cyclopentane-1, 2-diamine and trans-cyclobutane-1, 2-diamine is described. These diamines have been used as components of novel chiral salen ligands whose chromium and manganese complexes were then evaluated as oxygen transfer agents in the asymmetric epoxidation of alkenes.
