The present invention relates to an octahydro biquinoline compound. Provided is also a method of separating the octahydro biquinoline compound into enantiomers. The octahydro biquinoline compound is of the general formula (V): In formula (V) R1 is one of H, a protective group and an aliphatic group, with the aliphatic group having a main chain of a length of 1 to about 10 carbon atoms, comprising 0 to about 6 heteroatoms selected from the group consisting of N, O, S, Se and Si. R2 and R3 are independent from one another selected from the group consisting of (i) H, (ii) one of an aliphatic, an alicyclic, an aromatic, an arylaliphatic, and an arylalicyclic group comprising 0 to about 6 heteroatoms selected from the group consisting of N, O, S, Se and Si, an ester, a carbonate group, a carbamoyl group and a phosphate ester. R4 and R5 are independent from one another H, an aliphatic, an alicyclic, an aromatic, an arylaliphatic or an arylalicyclic group comprising 0 to about 6 heteroatoms selected from the group consisting of N, O, S, Se and Si.
