Abstract
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.
摘要
通过将N-BOC保护的氨基醇(1S,2S)-2-氨基-1-苯基-1,3-丙二醇和(S)-2-氨基-1,4-丁二醇与氯甲基苯甲酸氯化物反应合成了光学活性的两层和三层氮配体。通过氯甲基取代基的核苷亲核取代与N-甲基化(R)-1-苯基乙胺进行扩展。脱保护物质被N-苄基化,并与6,6'-双(溴甲基)-2,2'-联吡啶反应,形成了新的光学活性扩展联吡啶配体。
