Glycosides, Synthesis, and Characterization,e subject to internal nucleophilic addition to form cyclic hemiacetal structures. When the addition occurs between -OH at C(4) or -OH at C(5) with the carbonyl group, a five-or a six-member ring is formed known as a furanose or a pyranose, respectively. It is also known that equilibrium exists betwe

C-Glycosides,e increasing significance of .-glycosides is that the conformational differences compared to .- or .-glycosides are minimal and that they are resistant to enzymatic or acidic hydrolysis since the anomeric center has been transformed from acetal to ether. A glycoside is defined as .-glycoside when wh

Nuclear Magnetic Resonance of Glycosides,tural elucidation. Characterization by means of .H, .C NMR, mono- and bidimensional spectroscopy is a powerful tool for structural assignment of simple and complex glycosides. Pioneering studies on simple monosaccharides were essential for understanding through the chemical shifts and coupling const

X-Ray Diffraction of Glycosides,ion angles, which are necessary elements for understanding the conformation of glycosides. Improved diffractometers, faster computational processors, and newer mathematical programs have made possible the structural resolution of simple and complex substances of glycosidic nature particularly those
