【摘要】 以两种手性氨基醇作为主体,运用1H NMR分别考察其对客体7个扁桃酸衍生物对映异构体的手性识别能力。结果表明,主客体物质的量之比为1∶1时,主体诱导客体对叔丁基扁桃酸消旋体最高产生37.6 Hz的化学位移差值。更多还原

【Abstract】 The chiral recognition ability of these two chiral amino alcohols were evaluated as chiral solvating agent(host) for 7 mandelic acid derivatives enantiomers(guest) in the presence of an equimolar amount,respectively.As a result,the biggest chemical shift non-equivalences(δ) of 4-tert-butyl mandelic acid enantiomers induced by the two polydentate ligands was 37.6 Hz.更多还原
