Comprehensive Summary

With protoescigenin as starting material and through orchestrated application of Yu and Schmidt glycosylation protocols, the synthesis of acyl group-free escin derivatives was achieved for the first time. As the undesired non-specific toxicity, originating from the existence of acyl groups on aglycone, prohibits the wide application of escins, the established strategies toward non-acylated protoescigenin-type saponins would dramatically ease the access to escin derivatives dispense of acyl groups, thereby speeding up the pace of pharmaceutical use of these valuable compounds.
