Graphical Abstract:


A new method for the preparation of three new curcumin analogues is described by the connection of pentadienones to carbohydrate units. From L-Rhamnose and D-Galactose, several functionalization reactions were performed to obtain the desired sugar units. The sugars 8, 18 and 19, after obtained, were used as starting material for the association with curcumin-derived pentadienones, thus giving rise to three new chalcones 9 by O-glycosylation, 22 and 23 C-glycosylation. The new compounds were characterized by NMR and mass spectroscopy. The compounds obtained have high potential to exhibit antitumor activity.

Keywords: L-Rhamnose derivatives, D-Galactose derivatives, pentadienone, curcumin analogues, O-glycosylation, C-glycosylation.
