Probing subtle ligand effects in the enantioselective transfer hydrogenation of ketones
摘要:
The rational modification of an established amino-alcohol scaffold has revealed new, highly effective ligands for the enantioselective transfer hydrogenation of acetophenone that affords the product in up to 95% ee. (C) 2000 Elsevier Science Ltd. All rights reserved.

Breeding newcatalysts: A library of 1980 catalysts was designed for asymmetrichydrogentransfer to acetophenone. The library was submitted to evaluation and further simulated evolution experiments, based on a genetic algorithm (see scheme). We demonstrated that it was easily possible to get 5–6 of the ten best catalysts, while investigating only 10% of the library.
