Novel sophisticated derivatizing agents for the efficient enantioselective separation and mass spectrometric detection of d- and l-amino acids have been developed. Two new axially chiral reagents derived from 6,6'-dimethyl-2,2'-biphenyldiamine were synthesized. Their chiral separation and detection abilities were evaluated by
