Las enaminonas derivadas de 2-amino-2-deosi- -d-glucosa son excelentes sustancias de partida para obtener alquil-glucopiranosidos (o furanosidos). Las enaminoglicosas se obtienen tratando el aminoazucar con un conpuesto 1 3-dicarbonilico o un enol-eter de un conpuesto 1 3-dicarbonilico. La alquilación de las enaminonas por el método de fischer...

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 as a simple theoretical model based on energy-minimization calculations and MD calculations) reported herein support the...

Reductive amination of formyl C-glycofuranosides, easily available from hexose-derived equatorial-2-OH-glycopyranosides by DAST-promoted ring contraction, afforded N-substituted 1-C-aminomethyl glycofuranosides in most cases in high yield.

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 equatorial-2-OH-glycopyranosides by DAST-promoted ring contraction. © Georg Thieme Verlag Stuttgart New York.
