The synthesis of carbohydrate-based glycogen phosphorylase inhibitors is attractive for potential applications in the treatment of type 2 diabetes. A titanium-mediated synthesis led to a benzoylated C-glucosylated cyclopropylamine intermediate, which underwent a benzoyl migration to afford the corresponding 2-hydroxy-C-glycoside. X-ray crystallographic studies revealed a unit cell composed of four molecules as pairs of dimers connected through two hydrogen bonds. The deprotection of the benzoate esters under Zemplén conditions afforded a glycogen phosphorylase inhibitor candidate displaying weak inhibition toward glycogen phosphorylase (16% at 2.5 mM).
