This letter describes two unprecedented one-pot high yielding synthetic approaches to imidazo[1,2-a]pyridine scaffolds from carbohydrates. The first approach involves microwave-assisted acid-catalyzed domino reactions of unprotected d-glucose/d-xylose with ammonium acetate and benzoin to afford polyhydroxy iminosugar-bearing tetrahydroimidazo[1,2-a]pyridines. In the second approach, polyhydroxy iminosugar-bearing tetrahydrobenzimidazo[1,2-a]pyridines were synthesized by using unprotected d-glucose/d-xylose and 1,2-diamines in the presence of 10 mol % of oxalic acid under solvent-free microwave irradiation conditions.
