1-Deoxynojirimycin (DNJ), which has importance with respect to sugar processing enzymes, is a synthetic target for chemists. A key step in the synthesis of DNJ is the preparation of 2,3,4,6-tetra-O-benzyl-D-glucono-δ-lactam. By varying reaction parameters such as temperature, solvent and reducing reagent, improvements on previous methods are described. A novel approach for the synthesis of 2,3,4,6
1-脱氧野尻霉素 (DNJ) 对糖加工酶具有重要意义,是化学家的合成目标。DNJ 合成的关键步骤是制备 2,3,4,6-四-O-苄基-D-葡萄糖酸-δ-内酰胺。通过改变温度、溶剂和还原剂等反应参数,描述了对先前方法的改进。使用 PCC 作为氧化剂开发了一种合成 2,3,4,6-tetra-O-benzyl-5-dehydro-5-deoxo-D-gluconamide 的新方法。差向异构体的分离允许在还原和氢解步骤后以 85% 的产率获得 DNJ。
