PROCEDURE

实验过程

The galactose coupling agent 2-imino-2-methoxyethyl-1-thio-β-D-galactopyranoside (9) was prepared starting from 2,3,4,6-tetra-O-acetyl-α-D-galactopyranosyl bromide (6) in 3 steps via the intermediates 2-S-(2,3,4,6-tetra-O-acetyl-β-D-galactopyranosyl)-2-thiouronium bromide (7) and cyanomethyl 2,3,4,6-tetra-O-acetyl-1-thio-β-D-galactopyranoside (8) as shown in FIG. 5.
