Chemical treatment of diabetes mellitus is widely studied and controlling of blood glucose level is the main course of therapy. In type 2 diabetes mellitus, insulin resistance is the major problem. An isoflavone C-glucoside, puerarin (1), is known to enhance glucose uptake into the insulin sensitive cell and is thought to be a candidate for treatment of diabetes mellitus. We synthesized 1 and several

We completed the first totalsynthesis of puerarin (1), an isoflavone C-glycoside. The key intermediate, β-d-glucopyranosyl-2,6-dimethoxybenzene (9), was obtained by coupling of a lithiated aromatic reagent (3) with pyranolactone (2) in 56% yield. Condensation of (16) with p-methoxybenzaldehyde gave the chalcone (17). The protected chalcone (18) was cyclized to (19) in the presence of Tl(NO3)3. Demethylation
