Synthesis, thermal stability, antimalarial activity of symmetrically and asymmetrically substituted tetraoxanes

Symmetrically and asymmetrically substituted 1,2,4,5-tetraoxanes were synthesized by the oxidative system H2O2/TFE in presence of MeReO3 as a catalyst. All of the synthesized compounds were characterized spectroscopically, and evaluated for cytotoxicity, and antimalarial activity. Several of these tetraoxanes exhibited in vitro antimalarial activity without showing any cytotoxicity. Thermal stability of these compounds was studied by differential scanning calorimetry.
