[摘要]:Chiral diaminodiphosphine-ruthenium(II) complexes were found to be excellent catalysts for the asymmetric transfer hydrogenation of heteroatomic ketones in propan-2-ol. In the presence of potassium hydroxide, the enantioselective reduction of heteroaromatic ketones procceded smoothly to give chiral alcohols with excellent enantiomeric excess (up to 97% ee) under mild conditions without reduction of the heterocycle. |
