, p. 357 - 371 (2011/04/18)
The first synthesis of four natural triterpene saponins, which exhibit significant antitumor activities, was concisely achieved by adopting a stepwise glycosylation. The key intermediate 13 was afforded via Bu2SnO-mediated regioseletive benzoylation. Duri

scheme or table, p. 20 - 29 (2010/09/18)
Glucosidations of oleanolic acid (1) and its dihydroxy-olide derivatives (2) were carried out to provide eight glycosides. All synthesized compounds were evaluated by in vitro α-glucosidase inhibitory activity assay. 3-Acetyl dihydroxy-olide oleanolic der
