Abstract:
A general background to α-amino acids is discussed in the first chapter. After a brief account on classification, properties and applications of these compounds, asymmetric processes leading to optically enriched residues are reviewed in detail. The second chapter describes the envisaged stereoselective approach towards these substrates involving Michael-type addition onto a chiral didehydroalanine derivative. Syntheses of α,β-unsaturated amino acids are reviewed after a brief section on Michael-type reactions. The preparation of a chiral didehydroamino acid residue has been investigated using

Investigations of atom transfer reactions of amino acid derivatives are described in this thesis. Reaction of N-benzoylvaline methyl ester (29a) with sulphuryl chloride gave the β-chlorovaline derivative (30a) and lesser amounts of diastereoisomers of the r-chlorovaline derivative (31a). Studies of reactions of the valine derivatives (29a-c) with sulphuryl chloride, and of the photolyses of the corresponding N-chlorovaline derivatives (39a-c) have shown that the reaction of (29a) with sulphuryl chloride and the photolysis of (39a) involve regioselective intermolecular transfer of the respectiv

Functionalisation of the 3-alkyl-4-ketoprolines at C-4 has been investigated and a method has been found to prepare compounds which are functionalised stereospecifically at both C-3 and C-4.

The IR studies showed that glycine and ʟ-alanine coordinate monodentately through the amine nitrogen whilst the imidazole-carboxylic acid derivatives assume a bidentate chelation.

Abstract:
3-Methylaspartate ammonia-lyase is a bacterial enzyme that catalyses the reversible elimination of ammonia, in the presence of monovalent and divalent metal ions, from (2S,3S)-3-methylaspartic acid to yield mesaconic acid. The catalytic mechanism of the wild type enzyme obtained from Clostridium tetanomorphum involves a concerted elimination of ammonia and is thought to operate via the intermediacy of a dehydroalanine residue at the active site. No direct evidence has been established so far concerning the existence of this dehydroalanine residue, except that 3-methylaspartate ammonia-lyase wa
