Inside Back Cover: Seven‐Step Synthesis of All‐Nitrogenated Sugar Derivatives Using Sequential Overman Rearrangements (Angew. Chem. Int. Ed. 10/2021)

All-nitrogenated sugars (ANSs), in which all hydroxy groups a carbohydrate are replaced with amino groups, anticipated to be privileged structures useful biological activities. In their Communication on page 5193, Takaaki Sato, Noritaka Chida, and co-workers report the synthesis, transformation, tests of ANS derivatives. The key success was seven-step synthesis ANSs by sequential Overman rearrangement enabling formal simultaneous substitution four or five monosaccharides groups.
