Microwave-assisted Synthesis of Novel Chiral Receptors Derived from Deoxycholic Acid and Their Molecular Recognition Properties

Under microwave irradiation (MWI), novel chiral receptors derived from deoxycholic acid were synthesized by using deoxycholic acid methyl ester as the spacer, and arylhydrazine and amino acids as the arm. Selective recognition properties of these receptors for aromatic amines and D/L-amino acids have been investigated by UV-vis spectral titration and H-1 NMR spectral study. The results indicate this type of receptors can form a 1:1 supramolecular complex with an aromatic amine and a 1:2 supramolecular complex with D/L-tryptophan.
