Polymer-Immobilized Catalyst for Asymmetric Hydrogenation of Racemic α-(N-Benzoyl-N-methylamino)propiophenone
摘要:
Asymmetric hydrogenation of alpha-(N-benzoyl-N-methylamino)propiophenone through dynamic kinetic resolution was performed by using a polymer-immobilized chiral diamine-ruthenium-BINAP-t-BuOK system in order to yield syn-beta-amide alcohol exclusively with nearly perfect enantioselectivity.
Certain ethylenically unsaturated polymerizable monomers having a reactive carboxy group are useful for preparing homo- and copolymers for a variety of uses, including diagnostic assays. The polymers can be supplied as latex particles in aqueous compositions. The monomers are represented by the structure: ##STR1## wherein: R is hydrogen, halo or alkyl of 1 to 3 carbon atoms, M is hydrogen, an alkali metal ion or an ammonium ion, and L is a linking group having from 8 to 50 atoms in its linking chain, and comprises two or more divalent hydrocarbon groups connected or terminated with one or more nitrogen, oxygen or sulfur atoms, or with one or more groups containing such atoms in the linking chain, provided L has at least one arylene which is not directly connected to the terminal ##STR2## group, and further provided that none of the hydrocarbon groups has non-aromatic unsaturation.
