Article abstract of DOI:10.1246/bcsj.56.1414

This paper considers details on the mode of enantioface-differentiation process and the validity of a proposed sterochemical model, based on the following two series of investigations: 1) The hydrogenation of methyl acetoacetate over Raney nickel modified with NaBr and a compound whose structure is analogous to tartaric acid, and 2) the hydrogenation of various prochiral ketones over tartaric acid-NaBr- modified Raney nickel.
