Maitra, Uday and D'Souza, Lawrence J and Kumar, Vijay P (1998) Synthesis and cation binding properties of new bile acid-based crown ethers. In: Supramolecular Chemistry, 10 (1). pp. 97-106.Full text not available from this repository.
A series of bile acid-based crown ethers (7a-c,12 and 13) were easily constructed from readily available precursors. Measurement of association constants (K-a) with alkali metal picrates in CHCl3 showed that azacrown ethers 7a-c and Chola-Cuowns 12 and 13 show greater binding towards Rb+ and K+. The presence of the aromatic moieties showed subtle changes in the binding properties. Insight II minimized structures show very different conformations of aromatic units in 7a-b and 13.
