As a model for prebiotic sugar formation under neutral to acidic conditions, reactions of formaldehyde over hydrotalcite-type catalysts were investigated. Heating an aqueous solution of formaldehyde at 140—200 °C for 12 h over Ni–Fe hydrotalcite-type catalyst afforded 2-hydroxy-3,3-bis(hydroxymethyl)-γ-butyrolactone selectively, a 5.8% yield based on gas–liquid chromatographic analysis. The structure
作为在中性至酸性条件下形成益生元糖的模型,研究了甲醛在水滑石型催化剂上的反应。在 Ni-Fe 水滑石型催化剂上将甲醛水溶液在 140-200 °C 下加热 12 小时,选择性地提供 2-羟基-3,3-双(羟甲基)-γ-丁内酯,基于气体的产率为 5.8%液相色谱分析。通过 1H 和 13C NMR 和 1H-13C HSQC、HMBC 和 13C-13C 2D INADEQUATE NMR 实验确定了结构。
