The Hantzschthree-componentcondensation reaction of various aromatic aldehydes, 1,3-dione and aniline derivatives in the presence of 2-methylpyridinium trifluoromethanesulphonate ([2-MPyH]OTf) as green and highly efficient catalysts in water affords 1,8-dioxodecahydroacridine derivatives in good to excellent yields. This reaction has been carried out in the presence of 1 mol% of [2-MPyH]OTf at room

Reaction of aromatic aldehyde, 5,5-dimethyl-1,3-cyclohexanedione and p-toluidine in water were successfully carried out in the presence of p-dodecylbenezenesulfonic acid (DBSA) as a BrΦnsted acid-surfactant-combined catalyst. This method provides several advantages such as environment friendliness, high yields and simple work-up procedure. In addition, water was chosen as a green solvent.
