目的合成出驱镉效果好、毒副作用小的新型螯合剂。方法取甲硫氨酸在碱性水溶液中与葡萄糖进行氮保护反应,得第一步产物;在硼氢化钠存在下还原,酸化后减压、抽滤、冷冻干燥得第二步产物;在NaOH溶液中与二硫化碳/二氧六环反应,冻干得溶于水的黄色粉末,即为目标化合物D3。用氯化镉
Aim To synthesize a new type of chelator with good Cd removal and toxicity side effects. Methods Methionine was reacted with glucose in alkaline aqueous solution to obtain the first step product. The product was reduced in sodium borohydride, acidified and then depressurized. The product was filtered and freeze- The solution was reacted with carbon disulfide / dioxane and lyophilized to obtain a yellow powder which is soluble in water, which is the target compound D3. With cadmium chloride
