Synthesis of β-Glycosyl Formamides Through N-Glycosylation of Unprotected Carbohydrates
摘要:
Two new synthetic routes involving N-glycosylation of unprotected carbohydrates were developed for the preparation of beta-glycosyl formamides. Using this protocol, D-glucose, D-xylose, D-galactose and D-maltose were transformed to their corresponding beta-glycosyl formamides.
The structure of glycosyl amides: A combined study by NMR spectroscopy, X-ray crystallography, and computational chemistry
摘要:
The structure of N-formyl, N-acetyl-N-methyl, and N-acetyl glycosylamines has been studied by NMR spectroscopy in solution, single crystal X-ray diffractometry, and corroborated by PM3 semiempirical calculations. The results quite agree with an anti conformation around the glycosydic bond for these substances. (C) 1997 Elsevier Science Ltd. All rights reserved.
