Реферат: A new type of the four-component tandem Knoevenagel—Michael reaction was discovered. The transformation of arylaldehydes, N,N′-dimethylbarbituric acid, 4-hydroxy-6-methyl-2H-pyran-2-one, and morpholine in alcohols, other organic solvents, and water without a catalyst or any other additives and without heating leads to the selective formation of a new substituted unsymmetric ionic scaffold with three different heterocyclic rings in 81–98% yields. The structure of the obtained compounds was confirmed by the data of X-ray diffraction analysis.
