We reported a remote control glycosylation method using the picoloyl protecting group for 2-deoxy-β-glycosidic bond formation. The method is applicable to various 2-deoxythioglycosyl donors and the utility is illustrated by the synthesis of a deoxytrisaccharide component of landomycins.

A general synthetic strategy based on a protecting group-promoted CH arylation method was developed for total syntheses of anhydrolandomycinone (1), tetrangulol (2), and landomycinone (3) from the same set of starting materials.
