“…The most commonly used protocol for the synthesis of 1,8‐dioxodecahydroacridines involves reactions between aromatic aldehydes, dimedone and nitrogen sources such as ammonium acetate, hydroxylamines, aniline, ammonium bicarbonate and ammonium hydroxide . The previously reported catalysts for the synthesis of 1,8‐dioxodecahydroacridine derivatives are DCH (1,3‐dichloro‐5,5‐dimethylhydantoin), amberlyst‐15, SO 4 2− /ZrO 2 , nano‐Fe 3 O 4 @SiO 2 ‐SO 3 H, Brønsted acidic imidazolium salts containing perfluoroalkyl tails, ionic liquids, CAN, MNPs−N‐propyl‐benzoguanamine‐SO 3 H, Fe 3 O 4 @SiO 2 –MoO 3 H, silica iodide, KH 2 PO 4, FSG−Hf(NPf 2 ) 4 , MCM‐41‐SO 3 H, oxalic acid, SiO 2 ‐ZnCl 2, TPA NPs/PAA, magnetic titania‐SO 3 H, Fe 3 O 4 @DA‐SO 3 H, nano‐ferrite and n‐ZrSA …”
