Abstract

C-Alkyl glycosides represent an attractive class of nonhydrolyzable carbohydrate mimetics which possess enormous potential as next-generation therapeutics. Methods for the direct stereoselective synthesis of C-alkyl glycosides with a broad substrate tolerance are limited, however. This is especially in the case of β-linked C-alkyl glycosides, where direct methods for synthesis from commonly available coupling partners remain limited. This Account describes the evolution of our laboratory’s studies on glycosyl sulfonate chemistry from a method for the construction of simple β-linked 2-deoxy-sugars to a technology for the direct synthesis of β-linked acyl and homoacyl glycosides that can be elaborated into more complex structures.
