Conformational studies on pertrimethylsilyl derivatives of some mono- and disaccharides by 220 MHz PMR spectroscopy
TL;DR: In this article, a complete interpretation of 220 MHz PMR spectra and the accurate chemical shifts and coupling constants, obtained after computer simulation of the spectra, of a number of TMS-mono and disaccharides are given.
Journal ArticleDOI
Conformational studies of pertrimethylsilyl derivatives of 2-acetamido-2-deoxyaldohexopyranoses by 220- and 300-MHz P.M.R. spectroscopy
TL;DR: In this article, the authors presented a complete interpretation of high-resolution p.m. spectra and the accurate chemical shifts and coupling constants, obtained after computer simulation of the spectra, of the trimethylsilyl (TMS) derivatives of six 2-acetamido-2-deoxy- D -aldo-hexopyranoses are given.
Journal ArticleDOI
Conformational studies on pertrimethylsilyl derivatives of some 6-deoxyaldohexopyranoses and of four less-common aldohexopyranoses by 220-MHz P.M.R. spectroscopy. Substituent and configurational effects on the chemical shifts of the ring protons
TL;DR: In this paper, a complete interpretation of 220 MHz p.r. spectra and the accurate chemical shifts and coupling constants, obtained after computer simulation of the spectra, of the per-O -trimethylsilyl (Me 3 Si) derivatives of a number of 6-deoxy-aldohexopyranoses and of β- D -altro-, β - D -allo-, and α- and β-D -talo-pyranose are given.
Journal ArticleDOI
Conformational studies of per-O-trimethylsilyl derivatives of D-fructoses and oligosaccharides containing β-D-fructofuranose residues by 220- and 300-MHz P.M.R. spectroscopy
TL;DR: In this paper, the interpretation of 220-and 300-MHz P.R. spectra and the accurate chemical shifts and coupling constants of a number of per- O -trimethylsilyl-(TMS-) D -fructose derivatives and TMS-oligosaccharides containing β-D -fructofuranose residues are presented.
Journal ArticleDOI
The conformation of pentakis-O-trimethylsilyl-β-D-galactofuranose in solution as determined by 220-MHz p.m.r. spectroscopy
TL;DR: In this article, the authors studied the TMS derivatrve of J?-D-galactofuranose (TMS-j&D-Gal) and concluded that TMS-B+D-Galf occurs mamly in the “I?(D) envelope conformatron In the preferred conformatron of the C-4-C-5C-6 chain, H-4 and O-5, and also O-6 are m trans-coplanar arrangement.
