1. Regio-controlled and fast intermolecular heck reactions : palladium-catalyzed coupling reactions with microwave heating
Sammanfattning : .... LÄS MER
2. The mucus layer and other barriers to intestinal drug absorption
Sammanfattning : The extraepithelial mucus layer acts as a barrier to the absorption and diffusion of drugs. Three in vitro models have been used for studies of this and other intestinal barriers to drug transport. A drug absorption model based on monolayers of the mucus-producing human intestinal goblet HT29-H cell line was developed. LÄS MER
3. Palladium(0)-Catalyzed Synthesis of Spirocycles and Supercritical Chemistry using a Resistively Heated Flow Reactor
Sammanfattning : This doctoral thesis focusses on an effective and selective approach to the synthesis of spirocycles using palladium(0)-catalyzed Mizoroki-Heck reactions. In addition, selective and efficient chemistry was highlighted by the design and evaluation of a novel resistively heated system for continuous flow (CF) synthesis for high-temperature and high-pressure applications.

4. New Methods for the Synthesis of 3-Substituted 1-Indanones : A Palladium-Catalyzed Approach
Sammanfattning : In medicinal chemistry, there is a constant need for new preparative methods, both to make the synthesis process more effective, and to increase the accessibility to a wide variety of compounds. A number of different approaches can be used to attain these goals. LÄS MER
5. Palladium-Catalysed Carbon–Carbon Coupling Reactions : Focusing on Microwave Heating, Low Catalyst Concentrations, Aqueous Conditions, Regioselectivity and Medicinal Chemistry Applications
Sammanfattning : It is widely accepted that palladium is one of the most useful catalysts in organic chemistry, and many palladium(0)-catalysed carbon–carbon bond-forming reactions have been developed over the years. In addition, the ever-growing need for more environmentally benign processes in the chemical industry has driven scientists to look for greener options while developing new methodologies for organic synthesis.
