As the active component of precious Chinese medicine Aquilaria sinensis, 7,4'-dimethylapigenin-5-O-glycoside showed inhibitory activity for nitric oxide (NO) production by activated RAW 264.7 cells. Because of the strong intramolecular H-bond, the 5-O-glucosidic linkage in flavonoids could not be efficiently constructed via conventional glycosylation method. In this paper, the efficient chemical synthesis of 7,4'-dimethylapigenin-5-O-glycoside has been achieved for the first time starting from commercially available naringenin and D-glucose via a linear reaction sequence of 6 steps with the overall yield of 36.0%, wherein selective hydroxy protecting, reduction with sodium borohydride, glycosylation under phase transfer catalytic condition, oxidation with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) and other reactions were used. This work definitely laid the foundation for the further pharmacological study of this natural compound.

Key words: Aquilaria sinensis, 7,4'-dimethylapigenin-5-O-glycoside, flavonoids, chemical synthesis
