Stereospecific N-Glycosylation Strategy for β-N-Glycoside Synthesis via Base Catalysis.

-glycosides bearing heteroaryl, aryl, alkyl, and nucleobase functionalities. This approach features high yields and outstanding β-stereocontrol and obviates the need for traditional stereodirecting groups. Notably, late-stage modification of structurally complex drug molecules demonstrates the synthetic potential of this powerful approach.
