摘要
Preparation of optically active alkyl succinic acid monoalkyl esters (I) comprises enantioselective hydrogenation of ester compounds (II) in the presence of a catalyst, which carries a phospholane ligand (L). Preparation of optically active alkyl succinic acid monoalkyl esters of formula (I) comprises enantioselective hydrogenation of ester compound of formula (II) in the presence of a catalyst, which carries a phospholane ligand of formula (L). D, E : H or 1-10C alkyl; R : 1-10C alkyl, aryl or alkylaryl; R 21-6C alkyl, aryl or alkylaryl; R 1H or R 2; A : R 1or heterocyclic compound of formula (b); and B1 : bridge member with 1-5C between two P-atom or Cp-Fe-Cp.
