3,4,6-Tri-O-acetyl-D-glucal, also called 1,5-anhydro-2-deoxy-D-arabino-hex-1-enitol triacetate, is the acetate protected cyclic enol-ether (glycal) of D-glucose. 3,4,6-Tri-O-acetyl-D-glucal is a building block useful in the synthesis of a range of carbohydrates with the glucal double bond allowing other functional groups to be introduced. As an alkene, a glycal can undergo electrophilic addition across the double bond to introduce halogens and epoxides or be used to generate deoxy monosaccharides. 3,4,6-Tri-O-acetyl-D-glucal can undergo a Ferrier rearrangement with an alcohol and Lewis acid to give a 2,3-unsaturated product.

b-D-Allopyranose is a monosaccharide that has been modified with fluorine. It is used as a substrate for the production of oligosaccharides and polysaccharides, which are important biomolecules in cell walls and membranes. b-D-Allopyranose can be customized to suit your needs with Click chemistry, Methylation, or other modifications. We offer high purity b-D-Allopyranose at competitive prices.

4-Aminophenyl a-D-mannopyranoside is a compound that has been shown to have anti-inflammatory properties. It is also used as a starting material in the synthesis of other drugs. Rats with chronic kidney disease were given 4-aminophenyl a-D-mannopyranoside daily for three weeks, and it was found that this compound prevented the development of kidney injury markers. This drug has also been shown to be effective against mouse strains with nervous system diseases. 4-Aminophenyl a-D-mannopyranoside binds to lysine residues on proteins and prevents the interactions between these residues and the amino acid glutathione, which is required for glut1 uptake in brain cells. This uptake is essential for cellular function, and therefore 4-aminophenyl a-D-mannopyranoside may be useful as chemotherapeutic treatment for brain cancer.

Xylose (Xyl) is an aldopentose also known as wood sugar (Collins, 2006). The main sources of xylose are hemicelluloses found in hardwood and perennial plants, such as, grasses, cereals, and herbs (Petzold-Welcke, 2014) and some algae. Xylose is used in the production of xylitol, a low calory sugar substitute. Xylose is used in glycosaminoglycan (GAG) biosynthesis, which is initiated by peptide O-xylosyltransferases, which transfer xylose onto selected serine residues in the core proteins. The first enzyme in the pathway, peptide O-xylosyltransferase, catalyzes the transfer of xylose from uridine diphosphate (UDP)-α-D-xylose onto serine and thus determines the site(s) of GAG attachment on the core protein (Briggs, 2018).

3,4-Di-O-acetyl-D-arabinal is a spiroketal monofluoride that is known to be an efficient method for the synthesis of β-unsaturated aldehydes. It can be prepared by the hydration of enantiopure allyl chloroformate followed by reductive elimination with triflic acid and acidic hydrolysis. 3,4-Di-O-acetyl-D-arabinal has been used in the synthesis of biologically active molecules such as polyketides, peptides and natural products.
