Ruthenium-catalyzed enantioselective reduction of electron-rich aryl alkyl ketones

Wettergren, Jenny,Bogevig, Anders,Portier, Maud,Adolfsson, Hans

, p. 1277 - 1282 (2006)

Presented here is the investigation of the transfer hydrogenation of electron-rich aryl alkyl ketones using ruthenium complexes of dipeptide-like ligands and 2-propanol as hydride source. The reduction proceeded with excellent selectivity (up to > 99% ee) and in moderate to high yields (up to 90%).
