Aminomethylation of 6-hydroxy- and 6-hydroxy-7-methylaurones by the alkaloid cytisine was studied. It was shown that the aminomethylation of the 6-hydroxyaurones occurred at the 7-position of the benzofuran ring and at the 5-position if the 7-position was occupied.

therapeutic importance, also exist in variously glycosylated forms. Although a large number of glycosylated aurone derivatives have been isolated from plant sources, no syntheses have been reported yet. Inspired from this gap, here we report the firstsynthesis of peracetylated glycosyl derivatives of synthetic aurones. The direct O-glycosylation was achieved by reacting 6-hydroxy aurones with 2, 3, 4, 6-tetra-O-acetyl-α-D
