Second-Generation Synthesis and Analytical Application of TBBA for Chiral Analysis of Amino Acids and Oligopeptides by 1H and 19F NMR Spectroscopy
{{output}}
A concise and efficient second-generation synthesis of 2-(2-(trifluoromethyl)-1H-benzo[d]imidazol-1-yl)benzoic acid (TBBA) has been developed. The synthesis affording enantiomerically pure TBBA atropisomers was significantly streamlined through optical resolut... ...
