Chiral ferrocenyls

The invention relates to compounds of formula (I) wherein R1 is alkyl, cycloalkyl or optionally substituted phenyl; Ra-P (R 10 R 11) or -SR 12; R10-R12, -CH2-NH-R12, -CH2-O-P (R10 R11), R10 and R11 are optionally substituted alkyl, or R 10 and R 11 together form an optionally substituted alkylated alkylene; R'10 and R11 are the same as R10 and R11, with the proviso that -P (R10R11) is a non-identity of -P (R11R11); R12 is hydrogen, optionally alkyl, cycloalkyl or phenyl; R'12 is the same as R12, with the proviso that -SR12 is not the same as SR112; Y-OR13, -SR14 or -NR15R16; R13hidrogénatom, alkyl (C 1 -C 18) alkylcarbonyl or, optionally substituted phenyl; R14 is hydrogen, alkyl optionally substituted phenyl; R15 and R16 are optionally unsubstituted and / or substituted with one or more heteroatoms, arylene or carbocyclic groups; or -NR15R16cyclic amine; with the proviso that R1 represents a methyl group, and Y is other than dimethylamino when it is diphenylphosphino and Rb is di-tert-butylphosphino, or Ra is di-tert-butyl ) -phosphino group and Rb is diphenylphosphino group. The compounds of the present invention can be used as enantioselective reactions as ligands of transition metal catalysts. ŕ alkyl optionally substituted phenyl; R15 and R16 are optionally unsubstituted and / or substituted with one or more heteroatoms, arylene or carbocyclic groups; or -NR15R16cyclic amine; with the proviso that R1 represents a methyl group, and Y is other than dimethylamino when it is diphenylphosphino and Rb is di-tert-butylphosphino, or Ra is di-tert-butyl ) -phosphino group and Rb is diphenylphosphino group.
