3. Design and Synthesis of Novel Glutamine Synthetase Inhibitors and Development of Palladium(0)-Catalyzed Aminocarbonylation
Abstract : Tuberculosis (TB) is a major infectious disease, killing about 2 million people annually throughout the world. Today's TB treatment is a lengthy procedure involving a combination of antibiotics. No new TB drug has been introduced onto the market in the past 40 years, and the emergence of multi- and extensively drug-resistant TB calls for new drugs. READ MORE

4. Heck Reactions with Aryl Chlorides : Studies of Regio- and Stereoselectivity
Abstract : Homogeneous palladium-catalyzed Heck vinylation of aryl chlorides was investigated under air using Herrmann’s palladacycle and the P(t-Bu)3-liberating salt [(t-Bu)3PH]BF4. Based on the results, controlled microwave heating was utilized to accelerate model Heck reactions with aryl chlorides down to 30 min employing an electron-poor olefin and a mixture of an ionic liquid and 1,4-dioxane as solvent.
