The four hederagenin glycosides 1 – 4 were efficiently synthesized through one‐pot sequential glycosylations with glycose 1‐(trichloroacetimidate)s as donors, resulting in a significantly simplified synthetic procedure without isolation of glycosylation intermediates. The activity of the synthetic hederagenin glycosides 1 – 4 against α ‐glucosidase type IV was evaluated; hederagenin glycoside 4 containing an α ‐ L ‐rhamnopyranosyl unit showed the best activity with an IC 50 value of 47.9 μ M .
