1. Synthetic studies towards 7- and 8-membered N-heterocycles, particularly 1,4-pyrrolobenzodiazepines : total synthesis of fuligocandin A and B
Abstract : This dissertation is concerned with the synthesis of 7- and 8-membered N-heterocycles, particularly 1,4-pyrrolobenzodiazepines. A non-chromatographic method for conversion of carbonyl-functionalities to the corresponding thiocarbonyls is described. READ MORE

3. Iodotrimethylsilane-Promoted Conjugate Addition of Organocopper Reagents, DDQ oxidation of Arylpropenes and Synthesis of 2-Arylcoumarans
Abstract : This thesis is divided into three parts: conjugate additions of organocopper reagents, DDQ oxidations of arylpropenes, and synthesis and steric assignment of 2-arylcoumarans. The iodotrimethylsilane(TMSI)-promoted conjugate addition of alkylcopper and copper acetylides to certain a,b-unsaturated carbonyl compounds is investigated. READ MORE

4. Cellular toxicity of quinones : Redox- and addition chemistry
Abstract : Quinoid compounds are widely occurring in nature. They have cytotoxic properties and they are also used as antineoplastic agents. The cytotoxic properties can be explained by the ability of quinones to generate active oxygen species by redox cycling, by addition to cellular nucleophiles, and by inhibition of DNA transcription.
