中文摘要：

以文献报道具有显著抗肿瘤活性的化合物为先导化合物,以D-葡萄糖烯为原料经六步反应合成了一系列类似物,即取代的2-去氧-2-氯代-1-氨基糖。关键步骤是用（COCl）2-AgNO3-CH3CN体系高收率生成2-去氧-2-氯代-1-乙酰氨基糖,再经HCl-MeOH脱去保护基得目标化合物。经体外活性筛选,包括阳性药物在内的所有化合物均未表现出好的细胞毒活性。

英文摘要：

Using the potent anticancer agent 2-deoxy-2-chloro-1-amino sugar as a lead compound, its analogs were prepared in 6 steps starting from D-glucal. The key step was the synthesis of 2-chloro-1-acetamido sugars using （COCl） 2-AgNO 3-CH 3 CN system in high yields. 2-Deoxy-2-chloro-1-amino sugars were obtained by treating the corresponding acetamido sugars with HCl in MeOH. All the compounds, including the reference compound, displayed almost no cytotoxic activity to the selected cancer cell lines.
