A reaction sequence for the preparation of methyl 5-O-feruloyl-α-L-arabinofuranosyl-(1→3)-β-D-xylopyranoside, the companion 5-O-p-coumaroyl disaccharide, and their (1→2) analogs has heen developed. The (1→3) hydroxycinnamoylated disaccharides are availabl

Selective mono-benzoylation of some pento- and hexo-pyranosides (Me β-L-Ara, Ph α-L-Ara, Me α-D-Xyl, Me β-D-Xyl, Me α-D-Glc, Me-β-D-Glc, Me α-D-Gal, Me β-D-Gal, and Me α-D-Man) by using Bu2SnO was examined in comparaison with the results of the (Bu3Sn)2O method and direct benzoylation.The Bu2SnO method is particularly useful in that it selectively activates an equatorial hydroxyl group wich bears an oxygenated function (OH or OMe) in a cis relationship at an adjacent position, even in the presence of a more reactive primary OH group.The various mono- and di-O-benzoyl derivatives prepared in this work were unambiguously identified by analysis of their 13C-nuclear magnetic resonance spectra.
13C AND 1H NMR SPECTRA OF ALL METHYL O-BENZOYL-β-D-XYLOPYRANOSIDES. NONADITIVITY OF ACYLATION EFFECTS ON 13C CHEMICAL SHIFTS IN DEUTERIOCHLOROFORM SOLUTIONS
Petrakova, Eva,Schraml, Jan
, p. 877 - 888 (2007/10/02)
All methyl O-benzoyl-β-D-xylopyranosides have been prepared and their 1H and 13C NMR spectra measured in deuteriochloroform solutions.The 1H NMR spectra were analysed to the first order and assigned with the aid of homonuclear decoupling.The 13C chemical
