Abstract:
A catalyst composition for organic asymmetric synthesis comprising:(A) a lanthanoid element ion;(B) a binaphthol represented by the following general formula ##STR8##wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 independently represent a hydrogen atom, a straight chain, branched chain or cyclic alkyl group having 1 to 10 carbon atoms, a straight chain, branched chain or cyclic alkoxy group having 1 to 10 carbon atoms, a straight chain, branched chain or cyclic alkyloxyalkyl group having 2 to 10 carbon atoms, a straight chain, branched chain or cyclic alkyloxyalkoxy group having 2 to 10 carbon atoms, a straight chain, branched chain or cyclic alkylamino group having 1 to 10 carbon atoms, an aromatic group having 5 to 14 carbon atoms, an aromatic group having 5 to 14 carbon atoms and having a substituent which is an alkyl group having 1 to 5 carbon atoms, or a halogen atom; and * signifies that the carbon atom adjacent thereto is optically active; and(C) at least one compound selected from the group consisting of:(i) compounds represented by the following general formula (2): ##STR9##wherein R.sup.5, R.sup.6 and R.sup.7 independently represent a straight chain, branched chain or cyclic alkyl group having 1 to 10 carbon atoms, an aromatic group having 5 to 14 carbon atoms, an aromatic group having 5 to 14 carbon atoms and having a substituent which is an alkyl group with 1 to 5 carbon atoms, or a group represented by the following formula: ##STR10##wherein R.sup.8 and R.sup.9 independently represent a straight chain, branched chain or cyclic alkyl group having 1 to 10 carbon atoms, an aromatic group having 5 to 14 carbon atoms, a straight chain, branched chain or cyclic alkyl group having 1 to 5 carbon atoms and having a substituent which is an aromatic group with 5 to 14 carbon atoms, or an aromatic group having a substituent which is an aromatic group with 5 to 14 carbon atoms, and R.sup.8 and R.sup.9 may be combined together to form an alkylene group having 2 to 6 carbon atoms; and(ii) compounds represented by the following general formula (3): ##STR11##wherein A represents a carbon or nitrogen atom; and, when A is a carbon atom, R.sup.10 and R.sup.11 independently represent an amino group having two substituents each of which is a straight chain, branched chain or cyclic alkyl group having 1 to 10 carbon atoms, wherein R.sup.10 and R.sup.11 may be combined together with A to form a nitrogen-containing ring, or R.sup.10 and R.sup.11 independently represent an amino group having two substituents each of which is an aromatic group having 5 to 14 carbon atoms, and the bond between A and O is a double bond; and, when A is a nitrogen atom, R.sup.10 and R.sup.11 are combined together with A to form a nitrogen-containing aromatic ring, and the bond between A and O is a single bond.
