   <abstract xml:lang="ru">
    <p>The tetracarboxylic acids containing a cycloaliphatic fragment are promising monomers for semi-aromatic polymers of a series of polyimides, polyesters, and polyetherimides. An alternative method has been developed for their synthesis. The method demonstrates the possibility of performing alkylation and acylation reactions in sequence. The choice of the combination of methods for the oxidation of the acyl and methyl groups has been confirmed by quantum chemical calculations.</p>
