The present invention relates to a compound of general Formula Formula (XX), its formation and its use in asymmetric catalysis. In Formula (XX) R and R31 are independently -COOR3, -R4COOR3, -R4CHO, -R4COR3, -R4CONR5R6, -R4COX, -R4OP(=O)(OH)2,, -R4P(=O)(OH)2), -R4C(O)C(R3)CR5R6 and -R4CO2COR3. In addition, R31 may also be hydrogen. R3, R5 and R6 are independently hydrogen, an aliphatic group with a main chain having 1 to about 20 carbon atoms, an alicyclic group, an aromatic group, an arylaliphatic group or an arylalicyclic group, comprising 0 to about 3 heteroatoms independently selected from the group consisting of N, O, S, Se and Si. R4 an aliphatic bridge with a main chain having 1 to about 20 carbon atoms, an alicyclic bridge, an aromatic bridge, an arylaliphatic bridge or an arylalicyclic bridge, comprising 0 to about 3 heteroatoms independently selected from the group consisting of N, O, S, Se and Si, and X is halogen. In Formula (XX) R30 is -C(OH)R1R2 or -COOR14, wherein R1, R2 and R14 are independently hydrogen, an aliphatic group with a main chain having 1 to about 20 carbon atoms, an alicyclic group, an aromatic group, an arylaliphatic group or an arylalicyclic group, comprising 0 to about 3 heteroatoms independently selected from the group consisting of N, O, S, Se and Si. |
