Nitrogen-containing heterocycles derived from tetracarbonyl compounds and their analogs. Synthesis of 2-(4,4-dimethyl-2,6-dioxocyclohexyl)-1,4-diphenylbutane-1,4-dione and its reaction with N-nucleophiles

Article abstract of DOI:10.1007/BF02251998

Condensation of dimedone with 1,2-dibenzoylethylene in the presence of base gave 2-(4,4-dimethyl-2,6-dioxocyclohexyl)-1,4-diphenylbutane-1,4-dione. Its reaction with amines gives the corresponding pyrrole derivatives. 1999 KluwerAcademic/Plenum Publishers
