Toward fluorinated aminoglycosides: Structural studies of phenylhydrazine condensation with carbohydrate derivatives
(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 ...

Preparation of Chitosan-supported Urea Materials and their Application in Some Organocatalytic Procedures
(Elsevier, 2018)
An efficient and mild procedure was developed for the preparation of three chitosan-supported ureas containing electron-withdrawing groups. These catalysts were characterized and employed as organocatalysts in different ...

Synthesis of hyperpolarizable biomaterials at molecular level based on pyridinium-chitosan complexes
(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 ...

Easy Access to Configurationally Controlled C-Glycofuranoside-Based Building Blocks by Means of Formyl C-Glycofuranosides
(2010)
A general approach to enantiopure C-glycofuranoside-based hybridα/β-amino acids and nitrones, among other valuable building blocks, has been established via formyl C-glycofuranosides, easily available from hexose-derived ...
