【Abstract】 Chiral amine TMPEA was found to be useful in measuring of enantiomeric purityof chiraI ketones. Four pairs of diastereomeric ketimines were prepared from R-(- )-TM-PEA and dl-TMPEA with vari0us chiral ketones, the chemical shift differences between di-astereotopic protons (OCH,) were 0’ 085~0. 115, while fluorines (CF,) were 0’ 17~O. 45.
