Sonochemical synthesis of chromenes catalyzed by L-phenyl alanine-attached nano-Fe3O4@SiO2
An efficient multi-component synthesis of 10,10-dimethyl-7-(phenyl)-10,11-dihydrochromeno[4,3-b]chromene-6,8(7H,9H)-diones is described by a one-pot condensation reaction of aldehydes, dimedone and 4-hydroxycoumarin using L-phenyl alanine tethered to nano-Fe3O4@SiO2 under ultrasonic irradiation.
