By interaction of alpha-ketoglutaric acid with Schiff bases 1,5-diaryl-3-arylamino-4-carboxymethyl-2,5-dihydropyrrol-2-ones 1 were obtained. Hydrolysis of the latter, carried out with hydrochloride acid gave 1,5-diaryl-3-hydroxy-4-carboxymethyl-2,5-dihydropyrrol-2-ones 2. On treatment of 2 with aryl-amines the starting compounds 1 were yielded. All compounds were tested for their antiphlogistic activity.
通过α-酮戊二酸与席夫碱的相互作用,得到了1,5-二芳基-3-芳氨基-4-羧甲基-2,5-二氢吡咯-2-酮1。用盐酸对后者进行水解,得到1,5-二芳基-3-羟基-4-羧甲基-2,5-二氢吡咯-2-酮2。用芳胺处理2,得到起始化合物1。对所有化合物进行了抗炎活性测试。
