摘要
A series of dihydropyrano[c]chromene was obtained via condensation of aldehyde, malononitrile and 4-hydroxycoumarin in water catalyzed by morpholine, as a one-pot reaction. The significance of our findings relates to reducing the use of organic solvents, potentially toxic and hazardous materials, as well as its simplicity, good yields, mild conditions, and lower costs.
