were post-macrocyclization functionalized through the reduction of nitro groups and hydrolysis of the ester groups to obtain several derivatives of desired solubility. The difficulties in basic hydrolysis of ester groups were overcome via developing an acid hydrolysis method for tert-butyl esterderivatives of this class. The synthesis of symmetrical oxacalix[4]arenes from an unsymmetrically substituted
