A multicomponent reaction of arylglyoxal hydrates, acetylacetone or acetoacetic ester, aniline or its 3(4)-substituted analogs in 1:1:2 ratio occurred upon stirring in methanol, giving 4-arylamino-5-hydroxypyrroline derivatives containing 4,5-dihydroxypyrrolines as impurities.
在甲醇中搅拌时,芳基乙二醛水合物,乙酰丙酮或乙酰乙酸酯,苯胺或其3(4)-取代的类似物以1:1:2的比例发生多组分反应,得到含有4,5-二羟基吡咯啉的4-芳基氨基-5-羟基吡咯啉衍生物作为杂质。
