摘要

Direct β-glucosidation between benzyl alcohol and D-glucose (5) using the immobilized β- glucosidase from almonds with the synthetic prepolymer ENTP-4000 gave a benzyl β-D- glucoside (1) in 53% yield. The coupling of the benzyl β-D-glucopyranoside congener (8) derived from 1 with phenyl 2, 3, 4-tri-O-acetyl-1-thio-β-D-xylopyranoside (9), ethyl 2, 3, 4-tri- O-acetyl-1-thio-α-L-rhamnopyranoside (13), and 2, 3, 4-tri-O-acetyl-α-L-arabinopyranosyl ...
