The racemate of an inherently chiral meta-substituted calix[4]arene derivative 3 has been resolved via enantioselective HPLC. Measured optical rotation dispersion and electronic circular dichroism have been compared with DFT theoretical predictions. The comparison indicates that the absolute configuration of the dextrorotatory enantiomer (+)-3 is cS. The procedure has been successfully tested against a literature precedent confirming the validity of the method.

The silver-mediated nucleophilic substitution on calixarene p-bromodienone derivatives (the 'p-bromodienone route') with activated aromatic substrates allows the introduction of aromatic moieties at the para- or meta-position of calixarene aromatic rings.
