Abstract
A series of bile acid-based crown ethers (7a-c, 12 and 13) were easily constructed from readily available precursors. Measurement of association constants (Ka) with alkali metal picrates in CHCI3 showed that azacrown ethers 7a-c and Chola-Crowns 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.
