2-(N-Aryl)aminochromone-3-carbaldehyde does not show any change on heating in acetic acid, but under the same reaction conditions 2-(N-alkyl-N-aryl)aminochromone-3-carbaldehyde rearranges to 3-salicyloyl-2-quinolones, which exhibits antileishmanial activity.
2-(N-芳基)
氨基
香豆素-3-醛在
醋酸中加热时没有任何变化,而在相同反应条件下,2-(N-烷基-N-芳基)
氨基
香豆素-3-醛则重排为3-
水杨酰基-2-喹喏酮,后者表现出抗利什曼病活性。
