Bifunctional organocatalysis in the asymmetric Aza-Baylis-Hillman reaction
… thesis, 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 …

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
… been applied as solvents in the organocatalytic aza-Baylis-Hillman reaction, a rhodium-catalyzed hydrogenation, as well as in the synthesis of alpha-aminophosphonates using lanthanum triflate as catalyst. In the latter reaction diethylphenyl-(alpha-phenylamino)methylphosphonate could be observed …

DEVELOPMENT OF METAL-CATALYZED REACTIONS OF ALLENES WITH IMINES AND THE INVESTIGATION OF BRΘNSTED ACID CATALYZED ENE REACTIONS
… project is on the development of an unexpected aza-Baylis–Hillman-type reaction between ketoallenes and imine-containing electrophiles. This chemistry shows promise for a new single step, atom economical reaction for the generation of unnatural amino acids containing densely functionalized …

Chirale ionische Flüssigkeiten in der homogenen Katalyse
… of the anionchiral IL on the organocatalyzed Aza-Baylis-Hillman reaction was analyzed. Addition of the chiral IL led to a loss in selectivity and increased formation of a byproduct: through the hydrolysis of the substrate the corresponding aldehyde was formed. With low concentrations of the …
