| Enantioselektive Katalyse, 109 [1] Neue erweiterte chirale Bipyridine  | | | Abstract
| Optically active two and three layer nitrogen ligands were synthesized by reacting the N-BOC-protected aminoalcohols (lS,2S)-2-am ino-l -phenyl-1,3-propanediol and (S)-2-amino-1,4-butanediol with chloromethyl-benzoic acid chlorides. Expansion was carried out at the chlo-romethyl substituents via nucleophilic substitution with N-methylated (R)-l-phenylethylamine. The deprotected substances were N-benzylated and reacted with 6,6'-bis(bromomethyl)-2,2'-bipyridine to give the new optically active expanded bipyridine ligands. | | |
