Abstract:
This thesis describes the development of new osmium-mediated methodologies providing novel applications through the use of a third generation of reoxidant for osmium. Chapter 1, The introduction: Summary of past and present methodologies towards the synthesis of the 1,2 amino alcohol motif. Chapter 2, Intramolecular processes: The studies of the tethered aminohydroxylation (TA) of amide and urea derivatives are being investigated. Chapter 3, Investigations towards an intermolecular process: The transposition of the TA methodology to an intermolecular process and the requirements involved are discussed. The role of acetamide is being investigated. Chapter 4, Successful transition to an intermolecular process: Amino acid derivatives became for the first time possible nitrogen sources and were efficiently employed through osmium-mediated reaction to afford interesting biological scaffolds. Chapter 5, Experimental: Full experimental procedures and characterisation of compounds are reported. References: A complete list of citations employed in the previous five chapters is provided. Appendix: Full documentation of X-ray crystal structures, key NMR spectra and HPLC traces is provided.
