production of polyamides. This paper describes the synthesis of biobased succinonitrile from glutamic acid and glutamine, amino acids that are abundantly present in many plant proteins. Synthesis of the intermediate 3‐cyanopropanoic amide was achieved from glutamic acid 5‐methyl ester in an 86 mol % yield and from glutamine in a 56 mol % yield. 3‐Cyanopropanoic acid can be converted into succinonitrile, with
丁二腈是1,4-二氨基丁烷的前体,可用于聚酰胺的工业生产。本文描述了由谷氨酸和谷氨酰胺合成生物基琥珀腈的方法,谷氨酸和谷氨酰胺是许多植物蛋白中大量存在的氨基酸。中间体3-氰基丙酰胺的合成是由谷氨酸5-甲酯以86 mol%的收率和谷氨酰胺以56 mol%的收率完成的。通过使用钯(II)催化的乙腈平衡反应,可以将3-氰基丙酸转化为琥珀腈,选择性接近100%,转化率为62%。因此,发现了一种新的生产生物基1,4-二氨基丁烷的途径。
