Synthesis of 1-octadecyl 5-betainylamino-5-deoxy-β-d-fructopyranoside hydrochloride as a new long-chain cationic sugar-based surfactant

The synthesis of a novel long-chain cationic surfactant bearing a fructopyranoside polar head functionalized at the C-5 position by a natural glycine betaine residue through an amide linkage is described.
