Abstract
The synthesis of hydroxy-xanthone-3-O-β-glycosides by condensation of the appropriate aglycone and the acetyl-α-D-glycosyl bromide in pyridine solution in presence of silver carbonate is described. The naturally occurring l-hydroxy-3-O-β-primeverosyl-7-methoxy xanthone (gentioside) has been synthesized and its structure thereby confirmed.Keywords
