1. Regulation of HIV-1 mRNA Processing by Cellular Splicing Factors
Abstract : According to UNAIDS there were 34 million people living with human immunodeficiency virus (HIV) infection at the end of 2010. HIV is the causative agent of acquired immunodeficiency syndrome (AIDS) and the number of people dying of AIDS-related causes at the end of 2010 was 1.8 million. READ MORE

2. Synthetic studies of marine indole alkaloids and related systems
Abstract : This thesis is mainly focussed oil the synthesis of marine indole alkaloids and related systems, many of which display interesting biological activities. In the first part of this thesis we could establish and confirm the stucture of barettin and 8,9dihydrobarettin, isolated from the marine sponge Geodia baretti. READ MORE

3. C–H activation through late transition metal cyclometallation. Addressing selectivity and reactivity problems
Abstract : The ligand-directed C—H activation relies on a coordinating donor atom being in proximity to the C—H bond activated. Cyclometallation of 2-(1-naphthyl)-pyridine – a substrate containing both γ- and δ-positions in proximity to the directing nitrogen atom – was studied. READ MORE

5. Application of metalation reactions for synthesis of sulfur/selenium-containing heterocyclic compounds
Abstract : This thesis deals mainly with the synthesis of various sulfur/selenium-containing heterocyclic compounds, many of which include structural features present in several biologically active molecules, with particular emphasis on compounds of synthetic importance, such as indoles, as well as other heteroaromatic species. In the first part, an efficient procedure toward synthesis of new 3-(arylthio)indoles based on reactions of aryl Grignard reagents or lithiated heteroaromatics with protected 3,3′-dithiobisindoles is described.
