1-Deoxynojirimycin (1-DNJ) is a glycoprocessing inhibitor, and it serves as a synthetic precursor to two of three currently marketed iminosugar drugs, miglustat (N-butyl DNJ/Zavesca®) and miglitol (Glyset®). Herein a continuous flow procedure is presented that shortens a synthesis of 1-DNJ from an intermediate prepared from l-sorbose. Batch reactions involving an azide reduction, subsequent reductive
1-脱氧野尻霉素 (1-DNJ) 是一种糖加工抑制剂,它是目前市售的三种亚氨基糖药物米格司他 (N-butyl DNJ/Zavesca®) 和米格列醇 (Glyset®) 中两种药物的合成前体。本文介绍了一种连续流动程序,可缩短从l-山梨糖制备的中间体合成 1-DNJ 的时间。在先前的报告中,涉及叠氮化物还原、随后的基于还原胺化的环化和O-苄基脱保护的批次反应需要两个步骤并使用酸。在这里,这一顺序是使用 H-Cube® MiniPlus 连续流动反应器一步完成的。随后使用 H-Cube® 将 1-DNJ 与丁醛还原胺化,得到 NB-DNJ。
