The Amadori Rearrangement for Carbohydrate Conjugation: Scope and Limitations

Abstract

The Amadori rearrangement was investigated for the synthesis of C‐glycosyl‐type neoglycoconjugates. Various amines including diamines, amino‐functionalized glycosides, lysine derivatives, and peptides were conjugated with two different heptoses to generate non‐natural C‐glycosyl‐type glycoconjugates of the d‐gluco and d‐manno series. With these studies, the scope and limitations of the Amadori rearrangement as a conjugation method have been exemplified with respect to the carbohydrate substrate, as well as the amino components.
