Patent ID: 8691992

Claim:
An octahydro biquinoline compound of the general formula (V): wherein: R 1 is one of hydrogen, a protective group, and an aliphatic group, wherein the aliphatic group has 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, R 2 and R 3 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 with a main chain of a length of 1 to about 30 carbon atoms comprising 0 to about 6 heteroatoms selected from the group consisting of N, O, S, Se and Si, (iii) an ester group —C(O)—R 11 , (iv) a carbonate group —C(O)—O—R 11 , (v) a carbamoyl group —C(O)—N(R 11 )—R 12 and (vi) a phosphate ester —P(O)(OR 11 )—OR 12 , wherein R 11 and R 12 are independent from one another H or one of an aliphatic, a alicyclic, an aromatic, an arylaliphatic, and an arylalicyclic group with a main chain of a length of 1 to about 20 carbon atoms, comprising 0 to about 6 heteroatoms selected from the group consisting of N, O, S, Se and Si, and R 4 and R 5 are independent from one another H or one of an aliphatic, an alicyclic, an aromatic, an arylaliphatic and an arylalicyclic group with a main chain of a length of 1 to about 30 carbon atoms comprising 0 to about 6 heteroatoms selected from the group consisting of N, O, S, Se and Si.
