scheme or table, p. 1118 - 1121 (2012/01/15)
Amides and hydroxamic acids derived from α-amino acids were evaluated as ligands in combination with rhodium and iridium half-sandwich complexes in asymmetric transfer hydrogenation (ATH) of ketones. The reactions were performed in aqueous media using lithium formate as hydride source. The catalyst systems turned out to be highly efficient and ee's up to 90% were obtained.

A general, mild and efficient procedure with which to access hydroxamic acids, in good yields and purity, is reported. Esters are used as substrates and reacted with hydroxylamine, in the presence of a base, under microwave activation. The method has been
