Synthetic Route of 10343-06-3, An article , which mentions 10343-06-3, molecular formula is C14H20O10. The compound – 2,3,4,6-Tetra-o-acetyl-D-glucopyranose played an important role in people’s production and life.
2,3,4,6-Tetra-O-acetyl-D-gluco-, D-galacto- and D-mannopyranoses were tosylated with p-tolenesulfonyl chloride to afford their 1-O-tosyl derivatives which were cyclized “in situ” in a methanolic solution of sodium methoxide. 1,6-Cyclization products were obtained only with D-glucose and D-galactose derivatives.Cyclization of derivatives of D-glucose i.e. 2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosyl chloride, 3,4,6-tri-O-acetyl-1,2-anhydro-alpha-D-glucopyranose (Brigl’s anhydride) and 2,3,4,6-tetra-O-acetyl-alpha-D-glucopyranosyl bromide enabled the estimation of the influence of configuration at C-1 and C-2 on the course of cyclization.All product mixtures were separated by capillary gas chromatography (CGC) and their components were identified by coinjection with standards.
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 10343-06-3, help many people in the next few years., Synthetic Route of 10343-06-3
