Abstract:

Biocatalysts are increasingly prevalent in the large-scale synthesis of enantiomerically pure compounds. However, many sought-after reactions lack a suitable enzymatic production route. This work describes the development of a novel amine dehydrogenase through the application of directed evolution altering the substrate specificity of an existing leucine dehydrogenase scaffold. Eleven rounds of directed evolution completely altered the enzyme’s specificity and successfully created amination activity. The resulting amine dehydrogenase asymmetrically catalyzes methyl isobutyl ketone and free amm

Abstract:

The development of cost-effective and sustainable catalytic methods for the production of enantiomerically pure chiral amines is a key challenge facing the pharmaceutical and fine chemical industries. There is an increasing demand for broadly applicable synthetic methods which deliver the desired amine product in high yield and enantiomeric excess (e.e.). Previously we have described the development of variants of monoamine oxidase from Aspergillus niger (MAO-N) which are able to mediate the complete conversion of racemic amines to the corresponding enantiomerically pure products in a single s

Abstract:

Organocatalysis has become one of the most popular areas of research within organic chemistry over the past 15 years. This is due to the fact that, usually under mild conditions, it is possible to access either highly functionalized or previously inaccessible structural motifs using this relatively new type of catalysis. Firstly, methodology is reported for the synthesis and use of tertiary amine organocatalysts based on the now ubiquitous binaphthyl backbone. The tertiary amines synthesized were shown to be effective nitrogen transfer reagents in the asymmetric aziridination of chalcone subst

Hindering the degradation of amines in the CO2-capturing process is important both for economical purposes when it comes to loss of solvent and impacts on the process, and to prevent emissions of volatile degradation compounds such as ammonia, nitrosamines and formaldehyde.

Abstract:

This thesis will describe the development of a new route to homoallylic amines 9, in four steps from alcohols 1, or acetals 2, which may themselves have to be synthesised. The synthesis is stereoselective, and generates <i>E</i>-9 and <i>Z</i>-9 quite separately, thereby avoiding the sometimes difficult separation of these isomers. Alkenes 3, readily available from alcohols 1 or acetals 2, undergo regio- and stereo-selective 1,3-dipolar cycloadditions with nitrile oxides 4 or nitrones 6. The resulting heterocycles 5 and 7 are reductively cleaved to give β-hydroxy-δ-aminoalkyldiphenylphosphine
