was converted to methyl 3,4-di-O-acetyl-D-glucuronal applying a novel one-pot protocol, which allowed for large-scale synthesis. Introduction of silyl and benzyl groups was achieved using optimized procedures. Furthermore 3,4,6-tri-O-acetyl-D-glucal was used as starting material for an improved preparation of benzyl protected D-glucuronal, which significantly accelerates and simplifies similar methods
尽管将不同的受保护的D-葡萄糖醛酸用作制备许多化合物的前体,但文献中仍未描述标准方法和大规模合成方法。在开发不同的受保护d-葡萄糖醛酸基供体的过程中,我们开发了几种通用方法,可用于快速,可重复地制备大量关键中间体。应用新型一锅法将D-葡萄糖醛酸内酯转化为甲基3,4-二-O-乙酰基-D-葡萄糖醛酸,可大规模合成。甲硅烷基和苄基的引入是使用优化程序实现的。此外,将3,4,6-三-O-乙酰基-D-葡糖醛用作起始原料,用于改进的苄基保护的D-葡糖醛酸醛的制备,其显着加速并简化了文献中所述的类似方法。
