Claim:
A chiral selector for separating the enantiomers of a compound, comprising: a) at least one compound of formula (I): in which: W represents a bond, CR 4 R 5 , NR 4 , O or S; X represents CR 6 R 7 , NR 6 , O or S; Y represents CR 8 R 9 , NR 8 , O or S; Z represents CR 10 R 11 , NR 10 , O or S; R 1 represents OH or SH; and R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 , and R 11 , which are identical or different, represent: H; OH, SH; an amine group; an alkyl, haloalkyl or heteroalkyl group containing between 1 and 30 carbon atoms in a linear or branched chain; an alkenyl or alkynyl group containing between 2 to 30 carbon atoms in a linear or branched chain; one or more cycloalkyl, cycloalkenyl or cycloalkynyl groups containing between 3 to 30 carbon atoms in a linear or branched chain; one or more aryl or heteroaryl groups containing between 3 to 10 carbon atoms per ring; an alkaryl or aralkyl group containing between 1 and 30 carbon atoms, the terms aryl and alkyl having the definitions above; an alkoxy, thioalkyl, sulfonylalkyl or aminoalkyl group containing between 1 and 30 carbon atoms in a linear or branched chain; an alkoxyalkyl, alkylthioalkyl, alkylsulfonylalkyl or alkylaminoalkyl group containing between 1 and 30 carbon atoms in a linear or branched chain; one or more heterocyclic groups containing between 5 and 10 carbon atoms per ring; said groups all being optionally substituted by R 2 , by one or more nitro, cyano, hydroxyl, carboxyl, carbonyl or amino groups, by one or more halogens or by one or more nitrile, cyanohydrin or aldehyde functions; the compound of formula (I) being other than chitosan, neomycin, neomycin B, kanamycin A, kanamycin B, neamine, and amikacin; and b) at least one metal ion.
