Several oxazolidinones, a new class of synthetic antibacterial agents, have shown biological activity against multidrug-resistant gram positive organisms such as staphylococci, streptococci, and enterococci. Previous results of our studies with benzoxazolidinone phosphonate derivatives have demonstrated very low antibacterial activity. In the course of our studies directed towards the discovery of noble antibacterial agents, we have synthesized several new derivatives of oxazolidinone phosphonates prepared efficiently from commercially available amino acids. These compounds are tested for in vitro antibacterial activity and one of the compounds showed promising results allowing us to pursue further studies.

Several new derivatives of oxazolidinone phosphonate, that are expected to show biological activity, were prepared efficiently by previously published methods. ${\gamma}$-Ketophosphonate 1 was synthesized using pentacovalent oxaphosphorane chemistry followed by reductive amination with aromatic amine of oxazolidinone 4. Biological activity of the synthetic compounds has been studied. One of the synthetic compounds showed promising result for us to pursue further studies.
