- 論文の詳細を見る
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 Bu_2SnO was examined in comparison with the results of the (Bu_3Sn)_2-O method and direct benzoylation. The Bu_2SnO method is particularly useful in that it selectively activates an equatorial hydroxyl group which 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 ^<13>C-nuclear magnetic resonance spectra.
