The synthesis of 2-amino-2-methylglutaric acid from levulinic acid by Strecker’s method is reported. This acid gives 2-methyl-5-oxopyrrolidine-2-carboxylic acid on dehydration, and some of its esters were prepared and tested for plasticizer performance.
报告采用 Strecker 方法从乙酰丙酸合成了 2-氨基-2-甲基戊二酸。脱水后可得到 2-甲基-5-氧代吡咯烷-2-羧酸,并制备了其部分酯类,对其增塑剂性能进行了测试。
