The amine functionalities of chitosan have been reductively aminated with the aldehyde obtained by reductive ozonolysis of allyl α-D-galactopyranoside; the rheology of aqueous solutions of the products depends on the degree of substitution.

the molar ratio of glycoside to free amine groups of chitosan by between 0.5 and 3.0. Derivatives of degree of substitution >0.3 were typically water soluble, and compounds of higher d.s. generally gave less-viscous aqueous solutions. Assignment of 13C-n.m.r. chemical shifts verified the structure of these derivatives. The linewidths of the branch resonances (5–100 Hz) provided qualitative information

synthesis of neoglycoconjugates via oxime bond formation. These glycosyl aldehydes constitute a simple and accessible alternative to avoid loss of chiral information when conjugating, by oxime (or hydrazone) bonds, the aldehyde functionality present at the reducing end of natural carbohydrates. The straightforward preparation of glycosyl neoconjugates by oxime (or hydrazone) bond formation represents a key
