Abstract:

(2S)-trans-4-Hydroxyproline has been studied as a chiral template for the preparation of kainoids. Conversion to protected 4-ketoproline derivatives has allowed functionalisation at C-3 to be investigated. Although the tendency to epimerisation has caused problems, we have successfully introduced a variety of alkyl side chains with cis stereochemistry at this position. 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. These have potential for study as kai

Abstract:

This thesis is a multidisciplinary study of the solid state of squaric acid derivatives which combines approaches from areas such as crystal engineering, supramolecular chemistry and crystallography. The structural preferences in the solid state of this family of compounds has been analyzed, new crystalline materials derived from squaric acid have been designed in order to study new supramolecular synthons and relevant chemical phenomena such as template effect, preorganization, cooperativity and electrostatic compression have been explored. In summary, 47 polymorphs, solvates, cocrystals

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

Boronic acids are attractive synthetic intermediates and have been shown to be effective as inhibitors of various enzymes. In this project, the overarching goal is the selective inhibition of a protease present in the mitochondria known as human ClpXP. To study the potential selective inhibition of Human ClpXP using N-terminal peptidic boronic acid, we have designed a synthetic scheme that includes?-borylation of °,?-unsaturated carbonyl compounds using Cu(I) as catalyst, °-alkylation, saponification/hydrogenation, amidation, and oxidative removal of pinacolyl group with sodium periodate.

A number of 1-aminoalkanephosphonic acid derivatives incorporating physiologically Iabile groupings (ester, amide e.g. peptide, carbamate and tosyl) were prepared as a development from earlier studies in which certain phosphonic acid derivatives were shown to have previously unrecognised activity as fungicides. Such derivatisation might aid the translocation of the active phosphonic acid to the site of action. Compounds were screened for in vivo fungicidal activity against Drechslera teres.

Abstract:

As a class, amides are of great interest in biological studies and pharmaceutical application. In this work, podocarpic acid, a natural tricyclic diterpene, derived from Podocarpus species, has been employed to form a novel family of amide derivatives which will later be studied for their potential as new drug leads. Novel amide derivatives of podocarpic acid were synthesized from podocarpic acid in three steps. The first step involved methylation with dimethylsulfate to form methyl-O-methylpodocarpate. This step was followed by iodination with iodine to give iodomethyl-O-methylpodocarpate. Fi

In this work it was used for the synthesis of a series of derivatives with modifications at the C-3 and/or C-24 of the steroid skeleton. The series was prepared using simple chemical and showed good yields. Aiming

Abstract:

Podocarpic acid (a diterpenoid resin acid extracted from the Podocarpacea specie of plants) has shown cytotoxicity against carcinoma of the nasopharynx. Since this discovery has been made, research has been performed in order to alter the structure of the resin acid so as to increase the anticancer activity. The carboxylic acid and phenol functional groups, which are present in podocarpic acid, make it possible to synthesize new derivatives selectively at the C-15, C-13, and C-7 positions as well as by substitution of the phenol hydroxyl group. Thus numerous derivatives can be prepared, in hig

Methodology for the synthesis of polyfluorinated biphenyl benzylphosphonic acids was developed and various highly fluorinated phosphonic acid derivatives may be synthesised from the corresponding fluorobenzene system.

The use of these systems as self-assembled monolayers on AlOx was assessed by a range of surface-sensitive analytical techniques. The surface energy and work function of aluminium oxide (AlOx) may be altered upon the adsorption of monolayers formed of partially fluorinated benzylph

This highly regulated and tissue-specific modification is carried out by sialate- O-acetylesterase (SOAE) and sialate-O-acetyltransferase (SOAT) enzymes.
