1. Development and Applications of Molybdenum-Catalyzed Chemoselective Amide Reduction
Sammanfattning : This thesis covers the development of catalytic methodologies for the mild and chemoselective hydrosilylation of amides. The first part describes the investigation of the Mo(CO)6-catalyzed reduction of carboxamides. LÄS MER
2. Synthesis of N-Containing Compounds: Development of Methodology and its Application in Total Synthesis
Sammanfattning : This thesis aims to develop new synthetic methods and explore the possibilities to apply it in the total synthesis of natural products.Chapter 2 deals with a mild procedure for the synthesis of a-keto amides by a-oxidation of the corresponding aketo amines mediated by pyrrolidine and TEMPO. LÄS MER
3. Dynamic Chemistry for Asymmetric Synthesis, Molecular Motion and Constitutional Exchange
Sammanfattning : Living matter is built on complex dynamic systems consisting of numerus biotransformations. By exploiting the adaptive and evolutive behaviors ofmolecular matter, dynamic chemistry has developed as an important tool tounderstand the organization of nonliving matter into complex living systems. LÄS MER
4. Asymmetric Hydrogenations : Syntheses of Ligands and Expansion of Substrate Scope
Sammanfattning : Asymmetric hydrogenation has emerged as a versatile methodology to obtain a wide range of chiral precursors. This thesis focused on the synthesis of new chiral ligands and the expansion of the substrate scope of asymmetric hydrogenations. LÄS MER
5. Mechanistic and synthetic investigations of novel halogenation reactions of amidines and enamines with tetrahalomethanes
