Аннотация:A convenient synthesis of functionalized N-acylated amino acids containing 3- and 4-coordinated phosphorus moieties as well as N-alkoxycarbonyl groups has been developed. Aminomethylation of tricoordinated phosphorus acid esters with N-chloromethyl-substituted N-alkoxycarbonylamino acids proceeds under mild conditions and af ords new types of target products of dif erent structures. The resulting compounds are of interest as promising biologically active substances, ef ective extractants, and water-soluble polyden-tate ligands.
