Abstract :
Two new types of chiral calix[4](aza)crowns containing l-valine were synthesized by the reaction of calix[4]arene diacid dichloride with the corresponding chiral diamines derived from C2-symmetric chiral disulfonamides. Preliminary application of one ligand in chiral recognition was studied by 1H and 13C NMR, and UV spectroscopy.
