AbstractGlycoconjugates of the secondary metabolites exist abundantly in

plants, microorganisms, and lower marine animals. Many of those compounds bear complicated carbohydrate residues which occur as heterogeneous ‘glycoforms’, so that isolation of a homogeneous congener, especially in an appreciable amount, is always a formidable task. The poor accessibility remains as a hurdle for elucidation of the structure-activity relationships and the mechanism of action of glycoconjugates, which have shown a variety of the pharmacological activities. This lecture focuses on our synthetic accesses to the complex glycoconjugates of steroids and triterpenes, which are mostly from the traditional Chinese medicinal plants. Highlighted are new glycosylation methods which have been developed to tackle the emerged synthetic problems.
