[BMIm]BF4-LiCl: An effective catalytic system for the synthesis of pyrano[3,2-c]chromene and pyrano[4,3-b]pyrone derivatives
چکیده
An efficient and green method for the synthesis of pyrano[3,2-c]chromene or pyrano[4,3-b]pyrone derivatives is described by using a three-component condensation process of malononitrile, aldehyde, and 4-hydroxycoumarine or 4-hydroxypyrone in [BMIm]BF4-LiCl as an ionic liquid.
