An Efficient One-Pot Four-Component Synthesis of 9-Aryl-Hexahydroacridine-1,8-Dione Derivatives in the Presence of a Molecular Sieves Supported Iron Catalyst

“…Due to their importance, several strategies have been developed for the synthesis of 9-aryl-acridine-1,8-diones, including the thermal reaction of dimedone, different aromatic aldehydes and aqueous ammonia in ethanol [9], the microwave-irradiation-aided solvent-free reaction of dimedone and an aldehyde using alumina supported ammonium acetate and catalytic N,N-dimethylformamide [10], or ammonium bicarbonate [11], in water under microwave irradiation [12], and in pure water without any additives [13]. The use of ionic liquids alone [14,15] and in the presence of CeCl 3 •7H 2 O [16] was also reported for this conversion.…”
