Aryl Glycoside

A convenient protocol for β-stereoselective synthesis of 2-deoxy-C-aryl glycosides has been developed. This reaction takes place in one step by using I2/Et3SiH to activate glycosyl acetate to generate glycosyl iodide intermediate in situ, which was captured by naphthol followed by Fries-like O- → C-glycoside rearrangement to selectively afford β-C-aryl glycoside. The approach is applicable to a wide range of naphthol modules, and its utility was demonstrated in the synthesis of 5-aza analogues of Aquayamycin.
