Six dissymmetric calixarenes with C4 symmetry consisting of four 3,4-disubstituted phenolic units have been obtained by condensation of the respective 2- or 6-hydroxymethylated phenols.The regular incorporation of the phenolic units into the

Chiral calixarenes with C2 and C4 symmetry have been prepared and transformed into stable derivatives in the cone conformation.Their structures were established by 1H NMR and mass spectra and by an X-ray structure of a tetraester
