Hou, Jingke. "Compartmentalized enantioselective multicatalysis using polydimethylsiloxane membrane". Electronic Thesis or Diss., Ecole centrale de Marseille, 2022. http://www.theses.fr/2022ECDM0013.
Texto completo da fonteThe goal of this thesis was focused on the production of optically enriched enantiomers with complete consumption of racemic starting materials through newly designed double reactions system compartmentalized by a polydimethylsiloxane (PDMS) membrane with selective permeability. Firstly, the permeability of the PDMS membrane was studied showing a transfer selectivity of species depending on their polarity. Subsequently, the esterification and transesterification opposite reactions isolated by a PDMS membrane were performed to produce separated enantioenriched alcohols starting from racemic alcohols. However, we failed to set up such system due to the incompatibility of PDMS with the conditions of transesterification. Secondly, the compartmentalized parallel kinetic resolution combining two catalytic systems with opposite enantioselectivity isolated by a PDMS membrane was performed to produce both enantioenriched enantiomers, mirror image each other, isolated in each compartment starting from a racemic substrate. This concept was successfully established using the Jacobsen’s hydrolytic kinetic resolution of terminal epoxide. Each enantioenriched diol can be obtained up to 100% conversion from racemic epoxides. Thirdly, the compartmentalized dynamic kinetic resolution process combining a kinetic resolution and a racemization reaction isolated by PDMS membrane was performed to produce one single enantioenriched product starting from a racemic substrate. This enantioconvergent process allows to obtain an enantioenriched allylic ester up to 100% conversion from racemic allylic secondary alcohol circumventing the drawbacks of the incompatibility of the two catalytic system

Texto completo da fonteElaboration of synthetic methods based on metal-catalyzed reactions has been a hot topic in organic chemistry. Despite good efficiency, catalysis proceeding homogeneously, are limited in the operation of recovering/recycling of the catalysts. An important stress was placed to design catalysis, offering both the efficiency of homogeneous catalysts and the recyclability of heterogeneous catalysts. In this context, metal nanoparticles merged as a key tool, due to their unique physical and chemical properties. Notably, Au NPs have shown remarkable catalytic activity in the oxidation of activated alcohols under O2 atmosphere. Since now, the access to more complex molecules is the next step forward for this field, we envisioned multicatalytic roads, based on the oxidation of activated alcohols via supported Au NPs. Our choice of using solid catalysts was relevant, since nanostructured catalysts for which the fraction of active sites are located on the surface, limit the risk of cross-quenching. The latter carbonyl formed, could be further converted in situ, via tandem protocol. Herein, we developed novel, atom- and step-economical bicatalytic one-pot processes, to access substituted chromenes/quinolines (53-93%) by tandem oxidation/hetero-Michael addition/aldolisation combining nanocatalysis and base catalysis, ortho-THCs (50-81%) via tandem oxidation/arylation/cyclisation combining nanocatalysis and supported catalysts and a tandem cascade oxidation/hydrolysis to access HMLA (86%, sel 93%).

Lainer, Bruno. "A multicatalytic approach to enantio-, and diastereoselective arylation of alcohols". Electronic Thesis or Diss., Strasbourg, 2023. http://www.theses.fr/2023STRAF080.
Texto completo da fonteAlcohol moieties are present in a great diversity of valuable fine chemicals from nature and synthesis, therefore methods enabling their structural diversification are sought after. However, modifying the structure of alcohols at certain unreactive positions, even with the aid of catalysis, remains a challenge or requires tedious often wasteful multistep procedures. Recently, increased attention has been paid to multicatalysis, which combines multiple catalysts within one system, enabling the discovery of previously inaccessible reactivities or increasing the overall efficiency of multistep transformations. Described within are methods which enable the diastereo-, and enantioselective α-, and β-arylation of alcohols. By combining Ru- and Pd-based catalysts the unprecedented, enantioselective (and diastereodivergent in the case of alcohols already bearing stereocenters) β-arylation of primary alcohols can be carried out. Also, under sequential relay catalysis enantioenriched secondary benzylic alcohols can be obtained from a variety of available starting materials, such as primary alcohols, or alcohols bearing a double bond. Overall, these protocols demonstrate the potential of multicatalysis as a synthetic tool for diversifying alcohols. In a broader context, this thesis sets the stage for devising novel, multicatalytic strategies and methods for efficient synthesis
