Synthesis of D -Desosamine and Analogs by Rapid Assembly of 3-Amino Sugars
D-Desosamine is synthesized in 4 steps from methyl vinyl ketone and sodium nitrite. The key step in this chromatography-free synthesis is the coupling of (R)-4-nitro-2-butanol and glyoxal (trimeric form) mediated by cesium carbonate, which affords in crystalline form 3-nitro-3,4,6-trideoxy-alpha-D-glucose, a nitro sugar stereochemically homologous to D-desosamine. This strategy has enabled the syntheses of an array of analogous 3-nitro sugars. In each case the 3-nitro sugars are obtained in pure form by crystallization.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 112068-01-6, help many people in the next few years.Recommanded Product: (S)-Diphenyl(pyrrolidin-2-yl)methanol
