By utilizing anodic oxidation as the key reaction, various olean-12-ene sapogenols were readily converted into olean-11-en-28,13β-olide, 11α,12α-epoxy-oleanan-28,13β-olide, and 13β,28-epoxy-olean-11-ene derivatives, respectively in high yields.Since previous protection of hydroxyl groups in the starting compounds was not required, the conversion method was directly applied to hederagenin oligoglycosides and corresponding oligoglycosides of olean-11-ene sapogenols, functionalized as above, were successfully synthesized.KEYWORDS - anodic oxidation; olean-12-ene sapogenol; olean-11-en-28,13β-olide; 11α,12α-epoxy-oleanan-28,13β-olide; 13β,28-epoxy-olean-11-ene; triterpene oligoglycoside; Sapindus mukurossi
