Zusammenfassung / Abstract

The present work reports the results obtained from four projects. All of the studied processes proceed in conditions of asymmetric organocatalysis. The first project involves the development of a new Michael/Michael domino reaction for the synthesis of polysubstituted 1,2,3,4-tetrahydronaphthalenes. The second project includes the domino Mannich/cyclization sequence between alpha-ketoesters and tosylimines, affording 4,5-disubstituted 3-hydroxy-1H-pyrrol-2(5H)-ones. Next, the reaction between o-divinylketone and linear aldehydes was investigated, resulting in the construction of 1,2,3-polysubstituted indanes. In the last project, the enantioselective organocatalytic Friedel-Crafts-type Michael addition of electron-rich alkenes to nitroolefins was studied.
