C-linked carbo-β2-amino acids (β2-Caa), a new class of β-amino acid with a carbohydratesidechain having D-xylo configuration, were prepared from D-glucose. The main idea behind the design of the new β-amino acids was to move the steric strain of the bulky carbohydratesidechainfrom the Cβ- to the Cα-carbon atom and to explore its influence on the folding propensities in peptides with alternating
