Recommanded Product: 10343-06-3. Chemical engineers ensure the efficiency and safety of chemical processes, adapt the chemical make-up of products to meet environmental or economic needs, and apply new technologies to improve existing processes. 10343-06-3, Name is 2,3,4,6-Tetra-o-acetyl-D-glucopyranose. In a document type is Article, introducing its new discovery.
The X-ray analyses of 2,3,4,6-tetra-O-acetyl-alpha-D-glucopyran-osyl fluoride, C14H19FO9, (I), and the corresponding maltose derivative 2,3,4,6-tetra-O-acetyl-alpha-D-glucopyranosyl-(1?4)- 2,3,6-tri-O-acetyl-alpha-D-glucopyran-osyl fluoride, C26H 35FO17, (II), are reported. These add to the series of published alpha-glycosyl halide structures; those of the Peracetylated alpha-glucosyl chloride [James & Hall (1969). Acta Cryst. A25, S196] and bromide [Takai, Watanabe, Hayashi & Watanabe (1976). Bull. Fac. Eng. Hokkaido Univ. 79, 101-109] have been reported already. In our structures, which have been determined at 140 K, the glycopyranosyl ring appears in a regular 4C1 chair conformation with all the substituents, except for the anomeric fluoride (which adopts an axial orientation), in equatorial positions. The observed bond lengths are consistent with a strong anomeric effect, viz. the C1-O5 (carbohydrate numbering) bond lengths are 1.381 (2) and 1.381 (3) A in (I) and (II), respectively, both significantly shorter than the C5-O5 bond lengths, viz. 1.448 (2) A in (I) and 1.444 (3) A in (II).
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Recommanded Product: 10343-06-3. You can get involved in discussing the latest developments in this exciting area about 10343-06-3
