New enantiopure ligands I [RR1 = O(CH2)2O; RR1 = O; R = H, R1 = OH] contg. 2 (-)-5,6-pinenebipyridine units connected by a bridge situated in position 6' of the bipyridines were prepd. The chem. addressable groups of the bridge (hydroxyl or keto) can be covalently bound to various supports in order to heterogenize the ligand. [on SciFinder(R)]
