The straightforward and scalable syntheses of the triterpenoid saponins Anemoclemoside A and B are described. Both compounds feature an unusual cyclic acetal linkage to the carbohydrate l‐arabinose in its open chain form. A mild and facile method was employed to construct the characteristic cyclic acetal glycosidic linkage in both saponins via the PTSA catalyzed condensation of benzyl hederagenate
