由多元羧酸和手性2-氨基-1-丁醇经由相应的多元酰胺醇缩合制备了6个新型手性多噁唑啉,其结构经1H NMR谱、 IR谱、MS谱和元素分析确证;并应用这些手性多噁唑啉配体,初步探讨了苯乙酮在KBH4或NaBH4作用下的不对称还原反应.

Six novel chiral multioxazoline ligands were synthesized frommultiple acids and chiral 2-amino-1-butanol via the corresponding multi-β-hydroxylamide as successive intermediates, and their chemical structures were determined by 1H NMR, IR, MS spectra and elemental analysis. With these novel chiral multi-oxazoline ligands, the asymmetric reductive reaction ofacetophenone in KBH4 or NaBH4 was preliminarily studied.

Key words: multioxazoline, chiral reagent, asymmetric reduction, synthesis
