Calix[4]arene derivatives are used as a scaffold for the attachment of chiral substituents. Calix[4]arenes having either lower or upper rim capped with chiral binaphtholic species 5 and 6, as well as new biscalix[4]arenodiaza-18-crown-6 (8), have been synthesized.

Keywords: Calixarenes; Binaphthols; Chiral ligands.
