Abstract
Several chiral amino alcohols have been synthesized conveniently and effectively. 1H NMR was utilized to investigate their enantiodiscriminating abilities. Chiral amino alcohols 2 and 4 were discovered as efficient CSAs for the determination of the enantiomeric compositions of chiral carboxylic acids. In particular, for the Ts-derivatives of amino acids studied herein, 4 could be used for the assignment of the absolute configurations of the Ts-derivatives of amino acids with a neutral side chain through the chemical shift non-equivalences of their NH (Ts) protons with certain confidence.
