Article abstract of DOI:10.1055/s-1987-27904

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.
