A straightforward access to neohesperidose from naringin by acetolysis. Comparative behaviour of some flavonoid neohesperidosides and rutinosides under acetolysis

A straightforward semisynthesis of neohesperidose was performed in three-steps with 43% overall yield starting from naringin, the main flavonoid of grapefruit. In addition, the behaviour of two pairs of flavonoid 7-O-rhamnoglucosides (neohesperidosides naringin and rhoifolin; rutinosides hesperidin and diosmin) under same acetolysis conditions was compared. Results demonstrated the crucial influence of the oxidation state of the aglycone (flavanone or flavone), and of the nature of the disaccharidic moiety on the course of the reaction.

Synthesis of aryl glycosides as vir gene inducers of Agrobacterium tumefaciens

Aryl β-glycopyranosides have been synthesized by coupling syringaldehyde (3-methoxyvanillin) with L-fucose, D-galactose, and maltose; acetosyringone (4-hydroxy-3,5-dimethoxyacetophenone) with L-fucose and maltose; acetovanillone (4-hydroxy-3-methoxyacetophenone) with L-fucose; and syringic acid (4-hydroxy-3,5-dimethoxybenzoic acid) with D-galactose. The procedure using peracetylated glycosyl halides and sodium phenolates in aqueous acetone afforded the acetylated β-glycosides, which were deacetylated.
