described using 2–20 mol% FeCl3/C as the catalyst and benzylated propargyl glycosides as the donors to reach yields up to 96% under mild condition. With an octatomic-ring intermediate at the α-face of FeCl3/C with alkyne of propargyl glycosides, a panel of aglycones comprising aliphatic, alicyclic, unsaturated alcohols, halogenated alcohols, and phenols with different substitution were examined successfully

are the two main drawbacks of these reactions. The generality of the method, which was primarily developed as a solution to a carbohydrate problem, is shown by the successful hydrogenolysis of 1,8-naphthalide, a previously unsolved problem.
