摘要
在离子液体中,4-氨基安替比林和取代-3-甲酰基色酮反应,合成了4种含色酮环的Schiff碱(其中2种为新化合物),收率77%-94%,其结构经^1H NMR和IR表征。
Four Schiff base of aminoantipyrine chromones(3a -3d) in yields of 77% -94% were synthesized by the reactions of 4-aminoantipyrine with substituted-3-formylchromone in ionic liquid. Their structures were confirmed by ^1H NMR and IR. 3b and 3d were new compounds.
