Technical Notes:

1.Ligand for enantioselective Pd-catalyzed hydrogenation of enesulfonamides^[5]and cyclic N-

sulfonylimines^[6]

2.Enantioselective, asymmetric organocatalyst for3+2cycloaddition of allenoates to C60 fullerene (conversion >90%, ee up to 90%)

3.Ligand for Iridium-mediated direct asymmetric reductive amination of acetophenone with phenylhydrazide (conversion >99%; yield >94%; ee >94%)

4.Ligand used for the palladium-catalyzed, asymmetric, decarboxylative generation and asymmetric allylation of a-imino anions.

5.Ligand used in iridium-catalyzed, asymm etric hydrogenation of 6-substituted 3-hydroxypyridinium salts to trans 6-substituted piperidin-3-ols with high enantioselectivities(up to 95% ee).
