- W2809881443 abstract "This thesis describes the development of new methods towards the stereoselectivesynthesis of oxazolidinones and [3,3] sigmatropic rearrangements to allylamines fromallylic carbamate starting materials. Unlike previous protocols found in the literature theoxazolidinones formed do not have a protected nitrogen atom.The stereoselective formation of chlorohydroxylated products is demonstrated with theview to utilise this reaction as part of an alternative to the tethered aminohydroxylation.A novel diastereoselective iodine mediated cyclisation of allylic carbamates and allylicureas to oxazolidinones and imidazolidinones respectively is described. The reaction hasalso been telescoped from an aldehyde completing three reactions in a one potenvironment.The use of palladium (II) catalysis for oxazolidinone formation is also shown in an attemptto devise an enantioselective reaction analogous to the highly acclaimed tetheredaminohydroxylation. Palladium (II) catalysis is also utilised for the diastereoselectiveconversion of allylic carbamates to allylic amines.Chapter 1: An overview to the uses of osmium and palladium in the activation of alkenes described in the literature.Chapter 2: Highlights our research into the formation of oxazolidinone rings from and[3,3] sigmatropic rearrangements of allylic carbamates.Chapter 3: Provides experimental data for our studies." @default.
