Mesoporous silica anchored Ru catalysts for highly enantioselective hydrogenation of beta-ketoesters.

Recyclable and reusable mesoporous silica anchored Ru catalysts based on 4,4'-substituted BINAPs were synthesized and used for the hydrogenation of beta-alkyl beta-ketoesters with up to 98.6% e.e. and beta-aryl beta-ketoesters with up to 95.2% e.e.
