Toward fluorinated aminoglycosides: Structural studies of phenylhydrazine condensation with carbohydrate derivatives [Article]
(Georg Thieme Verlag, 2013)
The reaction of phenylhydrazine with a sugar dialdehyde in water, as a key step for the synthesis of the 3-amino-3-deoxy-d-glucose moiety contained in kanamycin, has been revisited. Structural studies (IR and NMR as well ...
Synthesis of hyperpolarizable biomaterials at molecular level based on pyridinium-chitosan complexes [Article]
(Universidade Federal do Espírito Santo, 2015)
Potential NLO-phore materials based on chitosan are described for the first time in this study. A series of fluorescent and quaternized pyridinium– chitosan derivatives have been synthesized by reaction of this polymer ...
