Abstract:

Reductively triggered internal cyclisation reactions have been investigated as a prodrug system for the hypoxia selective release of aromatic nitrogen mustards. The observed pseudo-first-order rate coefficients of cyclisation of several model 2-aminoaryl-acetamides and propanamides have been measured. Cyclisation was observed to be strongly influenced by stereochemistry, whereas electron withdrawal from the amine-bearing ring resulted in a comparatively modest slowing of the rate of cyclisation. Protonation of the leaving group appeared to increase the rate of cyclisation, while changes in 4-s

This thesis concerns the exploitation of the site isolation concept in cascade sequences that facilitate rapid construction of complex polycyclic molecules. Site isolation is the anchoring of mutually destructive reagents onto solid supports to prevent their mutual deactivation.

Abstract:

Introduction. The free radical cyclisation reaction onto an unsaturated bond is a well known synthetic pathway, where a wide range of cyclic compounds can be produced form acyclic starting materials. Up until recent years, free radical addition to multiple bonds other than carbon-carbon had been little studied. Nowadays there is much information available of radical addition to carbonyl, thiocarbonyl, nitrile and oxime ether (C=NOR) functional groups. However there has been surprisingly little detailed study of similar reactions involving imines (C=NR) or hydrazones (C=NNHR). Monocyclisation.

Abstract:

This dissertation is divided into five chapters. Chapter One consists of an introduction to radical cyclisation and rearrangement reactions. Chapter Two investigates the reactions of substituted arylsulfonamides 278a-l with copper bromide and an amine ligand-TPA. This reaction involves an alkyl radical generated from the copper (I) bromide/TPA complex, which can then undergo a 1,5- ipso attack onto the sulfonamide leading to a cyclohexadienyl radical intermediate. Re-aromatisation and extrusion of sulfur dioxide leads to an amidyl radical intermediate. This can undergo either cyclisation back

Abstract:

Boron trichloride, a cheap and commercially available Lewis acid, has been demonstrated to activate alkynes possessing appropriate nucleophiles, facilitating borylative cyclisation. This reaction furnishes polycyclic compounds possessing a new C(sp2)-B bond externally to the newly formed ring (through concomitant C-C and C-B bond formation). The RBCl2 intermediates generated from cyclisation were esterified with pinacol to furnish air/moisture stable boronic esters. This methodology has been applied to the following classes of starting materials: 1,4-disubstituted but-1-ynes (including N- and

Chapter 2 describes the initial model studies for the formation of the quaternary stereogenic centre using achiral cyclohexa-1,4-dienone derivatives.

Abstract:

The effect of scale on the conversion to products in flash vacuum pyrolysis experiments was studied using four model reactions. Overall, conversion was dependent on rection scale up to 0.5 g, but above 0.5 g, the effect was minimal and within experimental error. This effect was shown to be due to variations in contact time of the molecules in the furnace tube. Altering the furnace tube diameter had the effect of increasing the conversion to product. The pyrolysis of ortho-anilinomethylene Meldrum’s acid derivatives was investigated. Typically the 8-substituted quinolin-4-one was obtained as th

Treatment of b-phenylsulfanyl alcohols with acid results in the formation of episulfonium ions. These can be trapped intramolecularly to produce heterocycles.

In this case there is competition between two episulfonium ions and between two possible secondary hydroxyl nucleophiles. The cyclisation of compounds in which two episulfonium ions can form at the same centre, is also investigated. Finally, the interaction between the ring size (5-<i>vs </i>6-membered) and sulfur a

Three synthetic routes to cyclised pyrazole derivatives were investigated:- The first route was based on the chemistry of 2,3-diaminopyrazoles. Reactions with various electrophiles were carried out and some cyclised products were obtained. An important reaction with carbon disulphide was carried out and this resulted in the formation of the photographically important pyrazolo[1,5-<i>b</i>]1,2,4-triazole ring system. The second route explored the chemistry of 3-acetamidopyrazoles. Monoacylation of 3-aminopyrazoles was found to give a mixture of 1- and 2-acylated aminopyrazoles. The mixture surp
