The synthesis of two new furyl aminoacids as rigid isosteres of the dipeptides (D)-H-Ser-(D,L)-Thr-OH and (L)-H-Ser-(D,L)-Thr-OH is presented. The developed synthetic methodology starts from D-xylose and D-arabinose and makes use of trihydroxypropylfurans as intermediates. The key step of the strategy is the introduction of an amino function at the α-position of the adequate trihydroxypropylfuran

The synthesis of several non‐carbohydrate ligands of choleratoxinbased on polyhydroxyalkylfuroatemoieties is reported. Some of them have been linked to D‐galactose through a stable and well‐tolerated S‐glycosidic bond. They represent a novel type of non‐hydrolyzable bidentate ligand featuring galactose and polyhydroxyalkylfuroic esters as pharmacophoric residues, thus mimicking the GM1 ganglioside
