Reactions of calixarenes with methylaminoacetaldehyde dimethyl acetal and formalin gave Mannich bases with the calixarene platform. It was found by dielcometric titration that calix[4]resorcinols with acetal groups in the aminomethyl fragment form head-to-head supra-molecular aggregates in chloroform at low concentrations.

New amphiphilic benzylated calix[4]resorcinols were synthesized by the reaction of tetra-alkylcalix[4]resorcinols with 3,5-di(tert-butyl)-4-hydroxybenzyl acetate. The reaction pathway and the type of the products formed are determined by the structure of the alkyl substituent at the lower rim of tetraalkylcalix[4]resorcinols and the nature of acid used as a catalyst of the process.
