Both the sugar moieties and aglycons of steroid saponins play important roles for their bioactivities. In order to test the biological contribution of the glycosyl residue and search new saponins with notable anticancer activity, mono- and di-saccharide p

KHSO4-SiO2 can efficiently deprotect alcohols from esters through transesterification in methanol under mild condition. Esters of aromatic alcohols are easily transesterified at room temperature compared to the corresponding aliphatic or alicyclic alcohol. NAcetyl compounds and ethers are resistant to the reagent under the above condition. The method is very useful for preparation of biodiesel methyl ricinoleate from castor oil.
