19 - 035A Substrate Specific Chiral Modifier Activation on Enantio-Differentiating Hydrogenation over Tartaric Acid-Modified RaneyNickel. — A comparative study of the reactivities of the hydrogenation ofβ-ketoesters over tartaric acid-modified and unmodified Raney nickels indicatesthat a substrate specific chiral modifier activation is the reason for the almostperfect enantiodifferentiation in the reaction of 3-cyclopropyl-3-oxopropanoate(Ic). — (NAKAGAWA, SATOSHI; SUGIMURA, TAKASHI; TAI, AKIRA;Chem.
