Bifunctional organocatalysis in the asymmetric Aza-Baylis-Hillman reaction
… the mechanism of the Lewis base-mediated aza-Baylis-Hillman reaction was examined. Intermediates of the reaction were intercepted and structurally characterized, an extensive kinetic study was performed and the effects of Brønsted acidic co-catalysts on the reaction mechanism were examined. In …

Utilization of the Baylis-Hillman and related reactions in antiparasitic drug discovery
Baylis-Hillman adducts and compounds containing quinoline moieties have been previously utilized extensively in the search for antiparasitic agents. Work in this dissertation describes a series of compounds based on the Baylis-Hillman and the related three-component aza Baylis-Hillman reactions …

Entwicklung anion-chiraler ionischer Flüssigkeiten und ihre Anwendung in der Katalyse
… of anion-chiral ionic liquids (ILs) in catalytic reactions in order to investigate a potential chirality transfer. Thus chirality has been incorporated into the anion of the molten salt. There are several examples of catalytic reactions known in literature to be heavily influenced by the choice of …

New Methods for the α-Functionalization of Thioesters and Activated Hydrazones and an Application Toward the Total Synthesis of Apratoxin D
<p>Cascade reactions, also referred to as domino reactions, have been widely used for the formation of carbon-carbon bonds. This type of reaction has the potential to circumvent protection and deprotection steps, shortening an overall synthetic process.</p><p>The Morita-Baylis-Hillman (MBH) …

The origin of remarkable chromatographic differences in novel azulenyl-1,5-diols and synthesis and use of phosphinine and phosphabarrelene ligands for asymmetric catalysis.
… was also a successful organocatalyst of the Baylis-Hillman reaction, showing its versatility in both metal-catalyzed and metal-free catalysis.

Synthetic studies towards total synthesis of bielschowskysin
… with DIBAL-H. Initially, we relied on the Baylis-Hillman reaction to couple the two fragments. But in our hands, we were able to achieve the product in lesser yields. Finally, we were able to couple the two fragments using Pattenden?s alkylation methods. The future plans will be the …

Katalytische Festphasensynthese in Gegenwart von komprimiertem Kohlendioxid
… of compressed carbon dioxide on catalytic reactions on solid support was investigated. Pauson-Khand reactions (PKR) and hydrogenations were investigated representing reactions with gaseous substrates while the Baylis-Hillman reaction (BHR) was chosen because of its high negative reaction …

Chirale ionische Flüssigkeiten in der homogenen Katalyse
… of chiral reagents (such as catalysts) in the reaction of prochiral substrates. In this work, the use of chiral Ionic Liquids (IL = ionic liquid) as chiral reagent was investigated. The first part therefore addresses the synthesis and characterization of chiral ILs. The intention hereby was the …
