Reaction of resorcinarene octols with tris-hydroxymethylmethylamine (TRIS), formaldehyde, and alcohols results in tetraalkoxymethylation of the resorcinol rings. Harsh acylation of aminomethylated resorcinarenes with acid anhydrides leads to the complete acylation of eight hydroxyls and substitution of the amino versus acyloxy groups. Acyloxymethylated resorcinarene 6b can be transformed into a tetrabromomethylated

A series of aminophosphino cavitands were synthesized by reactions of dialkylaminomethyl-substituted calix[4]resorcinolarenes with hexaalkylphosphorous triamides, and their properties were studied. New aminoalkylated (thio)phosphato(phosphonato) cavitands were prepared by phosphorylation of dialkylaminomethyl-substituted calix[4]resorcinolarenes with phosphorus(V) dichlorides in the presence of a base. Their reactions with electrophilic alkylating agents (methyl trifluoromethanesulfonate, methyl iodide, and triethyloxonium tetrafluoroborate) were examined.

Deamination of dimethyl- and diethylaminomethylated tetraalkylcalix[4]resorcinarenes with 3,5-di-tert-butyl-4-hydroxyphenylmercaptan afforded new 3,5-di-tert-butyl-4-hydroxyphenylthiomethyltetraalkylcalix-[4]resorcinarenes. High antioxidant activity of the synthesized alkylcalix[4]resorcinarenes was established in the model reaction of initiated oxidation of styrene.

The crystal and molecular structure of previously unknown dimethyl- and diethylaminomethylated calix[4]resorcinolarenes was determined by X-ray diffraction, The calixarene molecules occur in the crystal in the cone form, stabilized by the system of hydrogen bonds at the upper rim of the macrocycle. The crystal structure of the dimethylaminomethylated derivative includes 4.5 benzene molecules and an ethanol molecule per calixarene molecule. No solvent molecules are located inside the macrocycle cavity. In the structure of the diethylaminomethylated derivative there is one benzene molecule per calixarene molecule. The benzene molecule is located in the macrocycle cavity. The supramolecular structure of crystals is analyzed.
