## Abstract magnified image In this paper the preparation of 3,3,6,6โtetramethylโ9,10โdiarylโ1,2,3,4,5,6,7,8,9,10โdecahydroacridineโ1,8โdione derivatives from aldehydes, aromatic amines and 5,5โdimethylโ1,3โcyclohexanedione in 1โnโbutylโ3โmethylimidazolium bromide ([bmim]Br) is described. The stru
Through multi-component condensation of aldehydes, 1,3-dione, Meldrum's acid, and ammonium acetate in an ionic liquid ([bmim][BF 4 ]), a series of 1,4-dihydropyridine derivatives were prepared in excellent yields in the absence of any additional catalysts. In addition, [bmim][BF 4 ] can be recovered
