designed, developed, and utilized to synthesize six high-purity 2-monochloropropanediol fatty acid esters (2-MCPD esters), a group of potential processing-induced food contaminants. A chlorine atom was introduced to C-2 of a diethyl malonate molecule, which was reduced by NaBH4 and followed by esterification using fatty acids. The reaction products were isolated and purified using silica gel columns to obtain
设计,开发并利用了一条新颖的合成路线,以合成六种高纯度的2-一氯丙二醇脂肪酸酯(2-MCPD酯),这是一组潜在的加工诱导食品污染物。将氯原子引入丙二酸二乙酯分子的C-2,将其通过NaBH 4还原,然后使用脂肪酸酯化。使用硅胶柱分离和纯化反应产物,分别得到三种2-MCPD单酯和三种二酯,产率分别约为50-54%和56-59%。另外,检查了2-MCPD单棕榈酸酯和双棕榈酸酯在瑞士小鼠中的急性口服毒性。LD 502-MCPD单和二棕榈酸酯的值大于5000 mg / kg体重(BW),以及可检测到的肾毒性和睾丸毒性。这项研究的结果可能会促进MCPD酯毒理学和检测的进一步研究。
