Synthesis and Evaluation of the Cholic Acid Derivatives with Multi-trifluoroacetylbenzoyl (TFAB) Groups as Carbonate Ionophores
Hyung-Jung Pyun, Jungho Chu, Woojin Yoon, Young Moo Jun, Dong Jin Kim
Several cholic acid derivatives containing 1-3 trifluoroacetylbenzoyl (TFAB) moieties were synthesized using selective acetylations, hydrolysis and/or oxidation of cholic acid derivatives and tested as receptors for a carbonate ion through solvent extraction method. The compounds having two and three TFAB moieties exhibited enhanced binding affinities toward a carbonate ion in comparison with those with one TFAB croup and the extent of complex formation also depended on the position of TFAB group attached.
