Abstract:

Signal Amplification by Reversible Exchange (SABRE) is a hyperpolarization technique that utilizes parahydrogen for the NMR signal enhancement of nuclear spins. SABRE is related to Parahydrogen Induced Polarization (PHIP), another means of hyperpolarization using parahydrogen; PHIP achieves hyperpolarization via chemical reduction. Although PHIP and SABRE share many similarities in experimentation, PHIP ultimately requires the presence of an unsaturated chemical bond as well as pairwise-addition of parahydrogen. No permanent chemical change occurs during SABRE, and instead may be considered as

Abstract:

<p>Palladium-promoted reactions have been employed for the synthesis of compounds labelled with <sup>11</sup>C (t<sub>½</sub> = 20.3 min). The precursor [<sup>11</sup>C]methyl iodide was used in palladium-promoted cross-coupling reactions with organostannanes. With this method, large molecules with several functional groups, that is prostacyclin analogues, have been synthesised in up to 54 % decay-corrected radiochemical yield, calculated from [<sup>11</sup>C]methyl iodide. However, since this method did not afford reproducible yields, a second method where copper(I) was used as a co-catalyst

Abstract:

Le marquage radioisotopique est un domaine d’intérêt d’un point de vue de la recherche fondamentale en santé et, de par ses nombreuses applications, aussi bien en industrie pharmaceutique et agrochimique que dans le milieu académique. Dans ce contexte, le carbone-14 joue un rôle primordial dans le développement de nouvelles drogues et dans les études ADME et toxicologiques. Les voies de synthèse traditionnelles impliquant le ¹⁴C sont longues et multi-étapes ce qui entrave la viabilité de cette stratégie. L’objectif de cette thèse est de développer de nouvelles techniques de radiomarquage par é

Abstract:

Plant cuticles are the interface for plant-environment interactions, and the first barrier protecting plants from environmental stresses such as water loss and pathogens. Structurally, the cuticle consists of a hydrophobic polymer lattice, cutin, and cuticular waxes deposited inside and outside cutin. The major components of the cuticular waxes are aliphatics derived from very-long-chain (VLC) fatty acids, such as alkanes and aldehydes. Besides compounds with primary functionalities, some compounds with two or more functional groups have also been identified in cuticular waxes. However, only l

Abstract:

This work deals with radiochemistry and new approaches to develop novel PET tracers labelled with the radionuclide 11C. Two methods for the synthesis of 11C-labelled acrylamides have been explored. First, [1-11C]-acrylic acid was obtained from a palladium(0)-mediated 11C-carboxylation of acetylene with [11C]carbon monoxide; this could be converted to the corresponding acyl chloride and then combined with benzylamine to form N-benzyl[carbonyl-11C]acrylamide. In the second method, the palladium(0)-mediated carbonylation of vinyl halides with [11C]carbon monoxide was explored. This latter method,
