In an article, published in an article, once mentioned the application of 10343-06-3, Name is 2,3,4,6-Tetra-o-acetyl-D-glucopyranose,molecular formula is C14H20O10, is a conventional compound. this article was the specific content is as follows.Quality Control of: 2,3,4,6-Tetra-o-acetyl-D-glucopyranose
A number of new glycosyl donors, O-(1-phenyl-1H-tetrazol-5-yl) glycosides, are prepared from the corresponding hemiacetals, commercially available 5-chloro-1-phenyl-1H-tetrazole (2), and tetrabutylammonium fluoride (Bu4NF) in either THF or DMF. The mild reaction conditions are compatible with a variety of protecting groups. The glycosyl donors are treated with hydrogen fluoride-pyridine complex (HF ¡¤ py) to rapidly provide glycosyl fluorides in good-to-excellent yields, apparently by a (single or double) S(N)2 mechanism as studied by both 1H- and 19F-NMR spectroscopy. Under acidic conditions, glycosyl fluorides equilibrate partially or completely, equilibration requiring a large excess of HF ¡¤ py.
