A novel hybrid macrocyclic receptorbased on bile acid and calix[4]arene has been synthesized using the α-face of the bile acid and cone-conformation of calix[4]arene. Metal recognition properties of receptor were investigated. The receptor showed the strongest affinity for Hg2+ in acetonitrile. The stoichiometry of the Receptor:Hg2+ was 1:1.

A bile acid based pyridino-triazole ligand to stabilize Cu(I) state has been developed. The ligand was found to catalyze click reactions of a number of alkynes and azides in presence of Cu(CH3CN)4.BF4 at very low catalyst loading and under milder reaction conditions.

A series of bile acidbased receptors having triazole unit along with some additional heteroatom containing moieties as coordinating units for transition metal ion recognition has been synthesized. The UV–Vis studies revealed that these receptors show significant multiple binding affinity for Hg2+, Cd2+, Pb2+ and Cu2+ ions.

1,3-Dipolar cycloaddition of propargyl esters of bile acids to azide group attached at different positions of bile acids gave dimers, trimer, and tetramer linked with 1,2,3-triazole. These dimeric and oligomeric structures were able to solubilize hydrophilic dye-cresol red, in nonpolar solvent. (c) 2007 Elsevier Ltd. All rights reserved.
