Description
  • 3beta-Acetoxy-21-oxolup-18-en-28-oic acid was used as a starting compound for oxidative cleavage by ruthenium tetroxide generated in situ from ruthenium dioxide by sodium metaperiodate in biphasic system. Tricyclic and tetracyclic acids baccharane type were prepared by this reaction and their structures were confirmed using spectral data. These acids were further used for synthesis of appropriate methyl and acetoxymethyl esters. All prepared compounds were tested on cytotoxic activity against CEM tumor cell line and several compounds showed activity in low micromolar concentrations.
