Massouh, Joe. "Transition metals-catalyzed C(sp2)-H bond activation for aldehyde functionalization." Electronic Thesis or Diss., Ecole centrale de Marseille, 2022. http://www.theses.fr/2022ECDM0001.
Повний текст джерелаThe synthesis of α-ketoacid, precursor or analogue of amino-acid, presents a center of interest. One of the synthetic pathways leading to these molecules could be the direct functionalization of aldehyde. The C(sp2)-H bond activation of aldehyde catalyzed by organometallic complexes is a powerful tool to afford various elaborated products in a relatively sustainable manner.In the first chapter of this manuscript, we presented the organometallic complexes based on different transition metals like Rh, Co, Ru, Ni, and Ir, that are able to activate selectively the C(sp2)-H bond of aldehyde. The reported procedures involve transition metals at low oxidation state favoring the oxidative addition mechanism, or at high oxidation state favoring the concerted metalation deprotonation process. This presentation allows to display the advantages and the drawbacks of each approach and highlights the novelty in each concept.In the second chapter, according to bibliography, procedures were investigated to achieve aldehyde C-H functionalization with various reagents, notably carbon dioxide. Various transition metals at low oxidation states were studied, and the reactivity of the aldehyde substrate remained restricted to the reported examples under Rh(I)-catalysis. In the case of high oxidation state transition metals, Rh(III)-catalytic complex was found efficient to mediate new pathway to imides using dioxazolones in good yields (up to 97%). Numerous parameters affecting the C-H activation of aldehyde were screened, and the mechanistic investigations were supported by labelling tests. Unfortunately, we observed that some catalytic systems, that are able to achieve aromatic C(sp2)-H bond functionalization with carbon dioxide, were not efficient to afford the carboxylation of aldehydic C(sp2)-H bond. The third chapter disclosed the experimental procedures and the characterization of the new products, notably imides

Повний текст джерелаDuring this thesis, we were interested in the sp² and sp³ C-H bond activation catalyzed by palladium catalysts for the preparation of (hetero)aryl-aryls and biaryls. This method is considered as cost effective and environmentally attractive compared to the classical couplings such as Suzuki, Heck, or Negishi. First we described the palladium-catalyzed direct C2-arylation of benzothiophene in the absence of phosphine ligand with high selectivity. We also demonstrated that it is possible to active both C2 and C5 C-H bonds for access to 2,5-diarylated compounds in one step, and also to non-symmetrically substituted 2,5-diarylpyrroles via sequential C2 arylation followed by C5 arylation. We also studied the reactivity of polychlorobenzenes via palladium-catalyzed C-H activation. We finally examined the palladium-catalysed selective sp² and sp³ C-H bond activation of guaiazulene. The selectivity depends on the solvent and base: sp² C2-arylation (KOAc in ethylbenzene), sp² C3-arylation (KOAc in DMAc) and sp³ C4-Me arylation (CsOAc/K₂CO₃ in DMAc). Through this method, a challenging sp³ C-H bond was activated

Повний текст джерелаThe direct functionalization of unactivated C-H bonds represents an atom- and stepeconomical alternative to more traditional synthetic methods based on functional group interconversion. Transition-metal catalysis has recently emerged as a powerful tool to functionalize otherwise unreactive C-H bonds. Whereas a lot of methodological studies have been developed in the past decade, few applications of these methodologies in multi-step or total synthesis have been reported in the literature. In this context, we envisioned the total synthesis of dibenzopyrrocoline alkaloids, a family of structurally original natural products, by using intramolecular C(sp3)-H arylation as a key step. This work led us to first develop a N-arylation / bromination / intramolecular C(sp3)-H arylation sequence which allowed us to access diverse fused tricyclic indolines. We next investigated the application of this strategy to the synthesis of the dibenzopyrrocoline motif. The difficulty to access the C(sp3)-H arylation precursor required an exploration of different synthetic pathways, which proved to be potentially promising. Finally the different performed methodological studies showed the feasibility of the intramolecular C(sp3)-H arylation of tertiary anilines, which was never described in the literature
