1,5-Dicarbonyl Compounds via Michael-Addition of Deprotonated Enamines and Allylamines to 2-(N-Methylanilino) acrylonitrile A new method for the synthesis of the title compounds by a onepot, three component, coupling reaction is described. Is consists of the reaction of a homoenolate anion and an enol cation equivalent with subsequent alkylation of an acyl-anion equivalent. Hence the methodology of Umpolung is used in a threefold manner within the reaction sequence.
