摘要：

The conformation of methyl 4-O-(beta-D-galactopyranosyl)-beta-D-xylopyranoside (1) and benzyI 3-O-(beta-D-galactopyranosyl)-beta-D-xylopyranoside (2) has been studied by NMR spectroscopy, assisted by molecular mechanics, molecular dynamics, and semiempirical methods. Both compounds show moderate flexibility and the shape of the global minimum of both molecules is very similar, although the xylose ring shows an important displacement when going from 1 to 2.
