Coupling of alkali metal ascorbates with benzyl halides and 2- and 3-hydroxymethylindole methanesulfonates resulted in L-ascorbic acid 3-O- and 2-C-derivatives. In contrast to 3-O-benzyl l-ascorbate, its indole analogs are unstable compounds, which underwent decomposition or rearrangement during isolation to give thermodynamically stable 2-C-isomers.
碱金属抗坏血酸盐与苄基卤化物和 2- 和 3- 羟甲基吲哚甲磺酸盐的偶联产生 L-抗坏血酸 3-O- 和 2-C- 衍生物。与 3-O-苄基 L-抗坏血酸酯相反,它的吲哚类似物是不稳定的化合物,在分离过程中会发生分解或重排,得到热力学稳定的 2-C-异构体。
