            摘要/描述

            3-O-b-Chacotriosyl-26-O-b-D-glucopyranosyl-(25R)-furost-5-en (1), a mimic of the antitumor active proto-dioscin, was concisely synthesized from diosgenin in a linear nine steps and in 17% overall yield. Its congeners with a a-L-rhamnopyranosyl, blactosyl, or without a substituent at the 26-OH (13-15) were also prepared. Compound 1, as well as 13-15, did not show any inhibition against tumor cells, implying that proto-dioscin might be also inactive, but readily converted into the antitumor active dioscin.
