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
