An efficientselective demethylation and debenzylation method for aryl methyl/benzyl ethers using magnesium iodideunder solvent-free conditions has been developed and applied to the synthesis of natural flavone and biphenyl glycosides. A variety of functional groups including glycoside were tolerated under the reaction conditions. Experimental results indicated that the removal of an O-benzyl group
