Abstract: Axially chiral 2-(2-(trifluoromethyl)-1H-benzo[d]imidazole-1-yl)benzoic acid (TBBA) was used as a chiral derivatizing agent to evaluate the limits of absolute configuration assignment for β-chiral aminoalcohols. Seven Boc-aminoalcohols and eight variously N-substituted (S)-phenylglycinols were prepared, and their TBBA… read more here.
