Dousset, Maxime. „Réaction d'expansion de cycle : études dirigées vers l'accès aux cycles de taille moyenne via des espèces polarisées“. Thesis, Aix-Marseille, 2017. http://www.theses.fr/2017AIXM0577.
Der volle Inhalt der QuelleIn the quest for new therapeutic candidates, the description of novel synthetic approaches to access to increasingly complex carbon systems remains a daunting challenge. In order to increase the structural of such scaffolds, it is necessary to overcome the encountered difficulties by developing new straightforward an efficient tools. In this context, this work has mainly focused on the access of structurally defined carbon cycles by ring expansion reactions via the use of polarized compounds. The first part of this study has been devoted to the Tiffeneau-Demjanov ring expansion reaction using ethyl α-chlorodiazoacetate. This approach allowed us to access highly versatile cyclic keto esters displaying a tetrasubstitued carbon center bearing a chlorine atom. The next topic of this study has been focused on the development of a (5 + 3) cycloaddition reaction between two polarized cyclopropane entities. This methodology led to the description of a novel reactivity of donor-acceptor cyclopropanes compounds to form α,β,γ-trisubstituted lactones under a BrØnsted acid activation. In order to gain mechanistic insights, a theoretical study has also been conducted which led us to rationalize the mechanism and the selectivity of this transformation. The last part described the reactivity of a underexplored class of molecule, the vinylbiscyclopropanes. These compound, can lead to the benzocyclobutene family and to the 8 membered-ring compounds through rearrangement or formal [3.3] sigmatropic rearrangement reaction. This last class of compound is still under study and should allow rapid access to diverse cyclic structures

Der volle Inhalt der QuelleThe identification of the middle sized organization as an intermediate firm asks the question of the enterprise's development process. The research of useful concepts in order to help the understanding of the firm's development can be implemented through a transversal approach to the management science, with the using of biological analogy. The evolutionary theory of the firm also integrate the life cycle theory as a level of observation of the organization development. It allows then a better understanding of its components. A model is then developed which study the dynamic relation between age, size and rate of growth of the firm. It is tested on a population of 1427 firms in basse- normandie with the integration of qualitative variables. Different behaviour can be found between growing-stage firms and maturity stage firms

Der volle Inhalt der QuelleEight-membered carbocyclic systems are widely represented motifs in natural and bio-active molecules. However, they remain under-represented in both marketed drugs and in drug discovery programs. This is mostly due to the well-known challenge of making them, due to the inherent ring strain. On the other hand, small rings represent a valuable three-atoms building element in the search to reach molecular complexity in an atom economical manner and often participate in fascinating chemical transformations. This release of ring tension usually allows for a scalable, rapid and controlled synthetic access to the expected target molecules. In this context, a new class of donor-acceptor cyclopropane (DAC) has recently been developed in the laboratory combining a silyl protected cyclopropanol with an α,β-unsaturated ester. Gratifyingly, the latter delivered polyfunctionalized cyclooctadienes in good yields in purely thermal conditions. The experiments ran in the laboratory demonstrated that the thermal rearrangement of DACs is totally regioselective and highly diastereoselective. A small library of highly substituted cyclooctanoïds was obtained without the need of any reagent nor transition metals. Finally, mechanistic investigations performed on selected DACs allowed us to better understand the course of the reaction and highlighted the formation of highly reactive trans-cyclooctadienes as intermediates, known for their high and unusual reactivity
