摘要：

The CD spectra of methyl 2-amino-2-deoxy-D-galactopyranoside mono-N-acylates (acetyl or p-bromobenzoyl) resemble those of the corresponding O-acylates and can be accounted for by the additivity rule. However, the CD of pyranosides containing the N-acetyl-p-bromobenzamido imide group (NAcBz) are far more complex than those of mono-N-acylates and their O-counterparts, and furthermore, the solvent- and temperature-dependent changes differ for the alpha- and beta-anomers. These differences can be accounted for by the different conformations of the 2-NAcBz group.
