CHAPTER ONE reviews the literature, discussing aspects of transition metal mediated asymmetric catalysis in the presence of enantiomerically pure ligands. CHAPTER TWO discusses the asymmetric addition of dialkyl-zinc reagents to aromatic aldehydes. The work presented is particularly concerned with the design and construction of enantiomerically pure oxazoline ligands tethered to alcohols These ligands have proved effective in the acceleration of the alkylation reaction and are able to influence good levels of asymmetric induction in the resultant secondary alcohol products CHAPTER THREE examines the electronic (and steric) effects of enantiomerically pure oxazoline ligands for the palladium catalysed allylic substitution reaction. Using ligands possessing two electronically different donor atoms, it is possible to create electronic distortion upon the intermediate allyl complex. In doing so it is possible to direct nucleophilic addition to one carbon centre preferentially to the other, resulting in asymmetric induction. Manipulation of these ligands enables control in the extent of electron distortion inflicted upon the allyl complex and consequently influences the levels of enantioselectivity observed. CHAPTER FOUR investigates the ability of hydrolytic enzymes to kinetically resolve a series of allylic acetates, under varying conditions. Lipases appeared superior to esterases for the substrates employed. In particular cis-3-acetoxy-5-carbomethoxycyclohexene was smoothly resolved m high yield and enantioselectivity. CHAPTER FIVE reports on the potentiality of a dynamic resolution of allylic acetates, using hydrolytic enzymes in the presence of a palladium catalyst. A proposed mechanism is discussed. Initial results are promising, however, the sensitivity of the reaction is realised and optimisation of conditions still needs to be addressed.
