Steroidal and triterpenoid saponins are attractive for their wide‐ranging pharmacological properties. The triterpenoid saponins Anemoclemoside A and B are root constituents of the Chinese folk medicinal plant Anemoclema glaucifolium (Ranunculaceae). Both compounds feature an unusual cyclic acetal linkage to the carbohydrate l ‐arabinose in its open chain form rather than the typical glycosidic bond present in normal saponins. The straightforward and scalable syntheses of both saponins starting from l ‐arabinose as well as l ‐lyxose and l ‐rhamnose are described.
