    • note
    • To the best of our knowledge, there has been no report on asymmetric desymmetrization of meso-diamine derivatives. In the reaction with diamine substrates, the enantiocontrol may be difficult because of high nucleophilicity of the amino group and the strong ability to chelate with transition metal, which may result in dissociation of the chiral ligand from the catalytic center and deactivation of the catalyst.

    • The reaction conditions in the conversion of Schemes 1 and 3 were not optimized, while as described in our previous paper,4 similar conversion with trisyl derivative 2a gave 4f in 46% yield.
