Reactions of methyl acetyl- or benzoylpyruvates with aromatic aldehydes and ethylenediamine, depending on the reactant ratio, afforded 4-acyl-1-(2-aminoethyl)-5-aryl-3-hydroxy-2,5-dihydro-1H-pyrrol-2-ones or 1,2-bis(4-acyl-5-aryl-3-hydroxy-2-oxo-2,5-dihydro-1H-pyrrol-1-yl)ethanes. Substituted 1-(2-aminoethyl)-3-hydroxy-2,5-dihydro-1H-pyrrol-2-one hydrochlorides were brought into reactions with p-methoxyaniline and hydrazine.
乙酰丙酮酸甲酯或苯甲酰丙酮酸甲酯与芳香醛和乙二胺的反应(取决于反应物的比例)可得到 4-酰基-1-(2-氨基乙基)-5-芳基-3-羟基-2,5-二氢-1H-吡咯-2-酮或 1,2-双(4-酰基-5-芳基-3-羟基-2-氧代-2,5-二氢-1H-吡咯-1-基)乙烷。取代的 1-(2-氨基乙基)-3-羟基-2,5-二氢-1H-吡咯-2-酮盐酸盐与对甲氧基苯胺和肼发生反应。
