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 ...
