  2. 1. Microwave-Assisted Synthesis of C2-Symmetric HIV-1 Protease Inhibitors : Development and Applications of In Situ Carbonylations and other Palladium(0)-Catalyzed Reactions

    Author : Johan Wannberg; Anders Hallberg; David C. Rees; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; HIV; protease inhibitors; palladium; carbonylations; molybdenum hexacarbonyl; dihydropyrimidone; DHPM; microwave; cross-coupling; diazylhydrazines; carbon monoxide; synthesis; C2-symmetric; HIV-1 protease inhibitors; aminocarbonylation; fluorous; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi;

    Abstract : The HIV protease is an essential enzyme for HIV replication and constitutes an important target in the treatment of HIV/AIDS. Efficient combination therapies using inhibitors of the reverse transcriptase and protease enzymes have led many to reevaluate HIV infections from a terminal condition to a chronic-but-manageable disease in the developed world.

  4. 2. Analysis of Industrial Microwave Ovens

    Author : Magnus Sundberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; source model; heat transfer; moment method; finite difference time domain; TM applicator; GMT; edge diffraction; thermal simulation; MMP; FDTD; generalized multipole technique; cost function; MM; optimization; magnetron; simulated annealing; multiple multipole program; microwave heating; edge overheating; TE applicator; tunnel-oven; applicator;

    Abstract : This thesis deals with the analysis and design of microwave ovens used in the food industry. Such analysis is desirable in order to optimize the performance of the ovens and to reduce the time and expenses of developing new or improved ovens. READ MORE

  5. 3. Fast Microwave-Enhanced Intra-, Pseudo-intra- and Intermolecular Heck Reactions

    Author : Andreas Svennebring; Mats Larhed; Anja Sandström; Erik Van der Eycken; Uppsala universitet; []
    Keywords : Pharmaceutical chemistry; palladium; Heck reaction; chelation control; microwave; Farmaceutisk kemi;

    Abstract : The Heck reaction is one of the most appreciated methods for carbon-carbon bond formation. Due to its mildness and ability to be tuned by additives, it often leaves few alternative competitive reactions. It has also proven easy to develop the reaction conditions in an environmentally benign direction. READ MORE
