trivalent organophosphorus acids to various functionalized acrylates and their cyclic analogues is proposed as convenient methods for the synthesis of new 2-trimethylsiloxycarbonyl-substituted alkylphosphonites and their derivatives under mild conditions. Also the new functionalized derivatives of these phosphonites, including amino, amido, and amino acids fragments as well as certain properties of these

contain fragments of bulky phenol along with hydroxymethyl groups and pyridine fragments and are promising complexones and antioxidants. As initial compounds we used accessible 2-pyridylethylphosphonites А that were successfully applied earlier to the synthesis of organophosphorous analogs of amino acids, containing amino and carboxy groups [3, 4]. Thus, phosphonites А readily added to the carbonyl group
