Synthesis of 1-[3,5-bis-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl)-2,4, 6-hihydroxyphenyl]ethanone : An intermediate of potential usefulness for synthesis of bis-C-glucosyl flavonoids

10.1016/S0008-6215(96)00280-7

The research aimed to synthesize 1-[3,5-bis-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl)-2,4,6-trihydroxyphenyl]ethanone, an intermediate compound that is potentially useful for the synthesis of bis-C-glucosyl flavonoids. The study focused on the bis-glycosylation of 3,5-dibenzyloxyphenol with 2,3,4,6-tetra-O-benzyl-α-D-glucopyranosyl fluoride in a two-step sequence, resulting in the bis-glucosylated product, 3,5-dibenzyloxy-2,6-bis-(2,3,4,6-tetra-O-benzyl-β-D-glucopyranosyl)phenol. The subsequent steps involved hydrogenolytic debenzylation and acetylation to yield the undeca-O-acetyl derivative, which was then subjected to Friedel-Crafts acylation with borontrifluoride-acetic acid to obtain the 4-C-acetyl target compound. The research concluded that this methodology is now available for the synthesis of bis-C-glycosyl compounds, and further syntheses of bis-C-glycosyl flavonoids are in progress.
