The asymmetric transfer hydrogenation of ketones using isopropyl alcohol (IPA) as hydrogen donor in the presence of novel manganese catalysts is explored. The selective and active systems are easily generated in situ from [MnBr(CO)5] and inexpensive C 2-symmeric bisoxalamide ligands. Under the optimized reaction conditions, the Mn-derived catalyst gave higher enantioselectivity compared with the related ruthenium catalyst.

Donor Source

A mild catalytic asymmetric transfer hydrogenation of a series of α-amino β-keto ester hydrochlorides catalyzed by a rhodium(III) complex is reported. The use of the formic acid/triethylamine system as the hydrogen donor source provided the corresponding anti and syn amino alcohols with complete conversions, fair diastereoselectivities (up to 97:3 dr), and high enantioselectivities (ee up to >99%).
