Chiral diamines 1-7 were used in the enantioselective hydrosilylation of prochiral aromatic and aliphatic ketones. Some of these ligands combine chiral backbones and chiral N,N′-α-phenylethyl substituents that give rise to synergistic effects between these two groups and lead to catalysts that exhibit high enantioselectivity.
trans-1,2-diaminocyclopentane-based catalyst for the asymmetric addition of alkyl-, aryl-, and vinyl groups to ketones

The catalytic asymmetric addition of ethyl-, phenyl-, and 1-hexenyl groups to ketones is reported. The new catalyst, generated from titanium wopropoxide and a bis(sulfonamide) diol ligand based on frans-1,2-diaminocyclopentane, gives good to excellent ena
