3,5-二甲基苯甲酰氯 | 3,5-dimethylbenzoyl chloride | 6613-44-1 | C9H9ClO | 168.623 |
Optically active two and three layer nitrogen ligands were synthesized by reacting the N-BOC-protected aminoalcohols (1S,2S)-2-amino-1 -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)-1-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.
