The synthesis of four GlcNAc(β1→4)Glc disaccharides containing 2‐O‐acetyl and/or 6‐sulfate groups was performed in high yields with total 1,2‐trans stereoselectivity. These disaccharides were evaluated as candidates for insect chitinase inhibition and aphicidal activity. All the compounds prepared displayed physiological effects on M. persicae aphids; however, the inhibition of chitinases of different
含有2- O-乙酰基和/或6-硫酸根基团的四种GlcNAc(β1→4)Glc二糖的合成产率高,总1,2-反式立体选择性。这些二糖被评估为昆虫几丁质酶抑制和杀蚜活性的候选者。所制备的所有化合物对桃蚜的蚜虫均显示出生理作用。但是,根据微妙的结构特征,不同来源(细菌,真菌和蚜虫)的几丁质酶的抑制作用遵循不同的模式。
