Methyl 4-O-(4-alpha-D-glucopyranosyloxy-4-methoxybutyl)-alpha-D-glu copyranoside (9) was synthesised by transacetalation from methyl 2,3,6-tri-O-acetyl-4-O-(4,4-dimethoxybutyl)-alpha-D-glucopyranosid e and trimethylsilyl 2,3,4,6-tetra-O-acetyl-alpha-D-glucopyranoside followed by removal of the blocking groups. Compound 9, which is methyl alpha-maltotrioside modified by replacing the middle D-glucosyl
甲基4-O-(4-α-D-吡喃葡萄糖基氧基-4-甲氧基丁基)-α-D-glu复制糖苷由甲基2,3,6-三-O-乙酰基-4-O-经缩醛化合成(4,4-二甲氧基丁基)-α-D-吡喃葡萄糖苷和三甲基甲硅烷基2,3,4,6-四-O-乙酰基-α-D-吡喃葡萄糖苷,然后除去保护基团。通过用无环间隔基代替中间的D-葡萄糖基残基而被修饰的甲基α-麦芽三糖苷化合物9,竞争性地抑制猪α-淀粉酶水解对硝基苯基α-麦芽三糖苷。
