Technical Notes:
1. Highly active highly enantioselective catalyst for hydrogenation of functionalized ketones. Slightly
higher temperature is necessary to activate the cymene complexes. See 15-0136
2. Asymmetric hydrogenation of a-substituted-ß-alkyl-ß-ketoesters accompanied by dynamic kinetic resolution.
