摘要
以Na_(2)CO_(3)为催化剂,采用无溶剂“一锅法”合成了5个苯并色烯衍生物,收率为79.6%~94.4%。以苯甲醛、丙二腈和间苯二酚为模板反应,通过单因素试验优化了反应条件。该法具有操作及后处理简单、反应时间短及环境友好等优点。
Using Na_(2)CO_(3) as catalyst,five chromene derivatives were synthesized by one-pot under free solvent in yields of 79.6%-94.4%.With benzaldehyde,malononitrile,and resorcinol as template reaction,the reaction conditions were optimized by single factor experiments.This protocol has the merits of simple operation,convenient work-up and short reaction time and environmentally benign.
