Full textBecause naphthalene has recently emerged as a fundamental platform in medicinal chemistry, the development of methodologies leading to diversely functionalised naphthalene-based platforms has become a prime concern of the scientific community. Indeed, experimental conditions previously optimised for benzene and other aromatic rings cannot always be applied to naphthalene. These methods can sometimes lead to different results, as a consequence of the lower aromaticity of the naphthalene core.In this context, this thesis is dedicated to the naphthalene and its derivatives. Various methods to selectively functionalise the different positions of the naphthalene core and synthetic pathways to extended polycyclic architectures were developed.Next, we focused on naphthalene precursors, especially on tetralones. Using a strategy involving a transient directing group, the position 8 of these bicycles was successfully arylated and the resulting compounds were successfully converted into other polycyclic platforms. In addition, DFT calculation have been used to explain the regioselectivity observed during the synthesis of extended fluorenones, and to study the mechanism of directed arylation of tetralones

Full textThis PhD thesis allowed us in the first part to develop different synthesic pathways to a new potential antipsychotic (F17464) invented by Pierre Fabre laboratories. Three strategies based on convergent syntheses are initiated. The key step of the first strategy is olefin cross metathesis. The second strategy rests on Sonogashira coupling and the third one involves a new methodology ofchromones alkylation in position 3. These methods allowed us access to novel synthetic intermediates, useful in the preparation of the F17464 molecule by following industrial confines.ln the second part, different types of polycyclic molecules were synthesized by palladium-catalyzed cascade reactions. A set of fused naphthalenes was prepared by palladium-catalyzed dominoreaction including cyclocarbopalladations followed by C(sp2)-H bond activation. Several types of fused seven-membered carbocycles were synthesized in a one-pot reaction from convenient substrates, via cascade reactions including cyclocarbopalladations followed by C(sp2 or sp3)-Hbond activation. Finally, cyclooctatrienes and fenestradienes were obtained also in a one-pot reaction from the same substrate via cascade reactions involving 4-exo-dig cyclocarbopalladation, followed by Stille coupling, alkyne addition onto a triple bond, finishing by electrocyclization reactions. Temperature is the only parameter that differs in the synthesis ôf the two complex polycycles starting from the same substrate

Full textThis thesis describes the preparation of alpha-tetralones using xanthate free radical chemistry and its application in organic synthesis. The work that has been established in the laboratory for several years permitted the elaboration of a route to substituted α-tétralones by radical cyclisation onto an aromatic ring. The reaction conditions used in this method are mild and a range of functional groups are tolerated. The α-tetralones prepared by this method were used as precursors for the synthesis of compounds of biological interest. Thus, new access to benzazepines, naphthalenes and C-arylglycosides were developed in the course of this work. The great applicability of these strategies was confirmed by the achievement of four total syntheses: the natural products 10-norparvulenone, O-methylasparvenone, tolvaptan and an analogue of tolvaptan were synthesised

Full textDuring the last few decades, electrochemical biosensors have been intensively investigated, due to their potential usefulness in clinical diagnosis and environmental survey. In this work, two reagentless and label-free electrochemical biosensors for direct detection of either a protein or a small organic pollutant have been studied. The first one is based on a juglone-peptide conjugate (JAP) and designed for the detection of XIAP, a cancer biomarker. JAP is co-polymerized with juglone on glassy carbon electrodes and the biosensor can detect in a specific manner the BIR3 domain of the XIAP protein with a detection limit of 1 nM (13 ng mL-1). The detection is highly specific in comparison with an unrelated protein and some negative control peptides. In addition, a double verification is performed to exclude all false positive results. This biosensor may be used as an early diagnostic method in certain cancer pathologies, involving high expression of XIAP. For the second one, bisphenol A (BPA) is immobilized on carbon electrodes according to the same strategy as above. The binding between the anti-BPA antibodies (a-BPA) and immobilized BPA induces a decrease of the electrochemical signal and the presence of BPA in a sample, depleting the antibody from the electrode, increases the signal. The biosensor has an excellent selectivity and a limit of detection as low as 2 pg mL-1, one of the most sensitive known. This sensitivity meets the requirement of environmental monitoring In conclusion, two electrochemical biosensors are successfully developed in this work to detect either a protein biomarker, XIAP or a small endocrine disruptor, BPA
