Повний текст джерелаDe entre todos los metales de transición utilizados en síntesis orgánica, el paladio ha ocupado un lugar central durante décadas y ha sido uno de los metales que más ha contribuido al desarrollo de este campo. En la presente Tesis Doctoral se han desarrollado diversas metodologías para la síntesis de heterociclos nitrogenados basados en procesos dominó catalizados por paladio. Por otro lado, los estudios experimentales se han combinado con estudios computacionales DFT para desentrañar el mecanismo implicado en estas transformaciones. En la primera parte de la Tesis Doctoral se ha llevado a cabo un extenso estudio de la reacción de α-arilación intramolecular de sulfonas catalizado por paladio. La combinación de la reacción de α-arilación con la subsiguiente adición conjugada a diversos aceptores de Michael, ha permitido el desarrollo de procesos dominó en 2, 3 y 4 etapas para la síntesis de tetrahidroisoquinolinas e indoles diversamente funcionalizados. Los estudios computacionales DFT de este proceso para la formación de indoles sugieren que la reacción de α-arilación transcurre mediante un proceso de desprotonación-metalación concertado (CMD) seguido de una eliminación reductora.

Aunque los tres tipos de nucleófilos pueden utilizarse en la reacción de α-arilación para la preparación de tetrahidroisoquinolinas, la reacción transcurre de manera menos eficiente en relación a las sulfonas estudiadas. Asimismo, la versatilidad de los procesos dominó desarrollados a partir de ésteres sulfónicos y sulfonamidas fue menor. Por otro lado, los fosfonatos han resultado ser completamente inactivos en los diferentes procesos domino estudiados. La reacción de α-arilación de sulfonatos, sulfonamidas y ésteres sulfónicos también se ha estudiado computacionalmente. Estos estudios han puesto de manifiesto que la reacción transcurre por mecanismos distintos en función del nucleófilo y de la base utilizada. En la segunda parte de la Tesis, se ha estudiado la viabilidad de los complejos de paladio en reacciones de inserción de carbenos en enlaces C-H generados a partir de α-diazoacetamidas. La descomposición de las α-diazo-α-(metoxicarbonil) acetanilidas catalizadas por complejos de paladio ha dado lugar a la formación de oxindoles como resultado de una inserción quimioselectiva en el enlace Csp2-H. Aunque tanto los catalizadores de Pd(0) como los de Pd(II) pueden promover esta reacción de inserción, los mejores resultados se han obtenido al utilizar complejos de Pd(0), en especial Pd2(dba)3 o [(IMes)Pd(NQ)]2. Los cálculos computacionales DFT de este proceso sugieren que la inserción tiene lugar mediante un mecanismo por etapas inédito que implica una migración 1,5 de hidrógeno promovida por el paladio seguido de un proceso de eliminación reductora. Finalmente, también se ha estudiado la descomposición de α-diazo-α- (metoxicarbonil) acetamidas catalizada por paladio para promover inserciones Csp3-H y la formación de β-lactamas. Aunque tanto los catalizadores de Pd(0) como de Pd(II) son capaces de promover esta reacción, los catalizadores de Pd(II) son más eficientes y versátiles.

Повний текст джерелаIn our ongoing course dedicated to the discovery of small anticancer molecules, we designed novel quinone derivatives. Our first objective was to fashion non-peptidic Smac mimics, able to trigger apoptosis in tumor cells, displaying a structure rigidified by conformational restrictions. Otherwise, the kinases and the phosphatases, acting as phosphorylating / dephosphorylating agents mostly in the control of the cell cycle, were thought to be other relevant biological targets. An intent study of their known inhibitors allowed us to underline trends in their chemical structure and made us plan the synthesis of functionalized naphthoquinones.A dedicated approach involving radical decarboxylation of amino acids allowed the introduction of aliphatic side chains on our substrates though C(sp2)–C(sp3) bond formation. Ag(I)/S2O82- was used as alkyl radical initiator and the direct C-H alkylation of the quinonic positions could take place. C(sp2)–C(sp2) bonds were created through aryl radicals generation from stable diazonium salts or anilines which allowed the direct C-H arylation of quinones. The procedures described along this manuscript let us formulate several advances on the substrates reactivity and on the reaction mechanisms involved

Повний текст джерелаIn this thesis we have been interested in the synthesis of arylated heterocycles via the activation of sp2 C-H bonds of heteroaromatics and to the synthesis of halo-substituted arylated alkenes using palladium-catalysis. The products obtained are considered to be molecular bricks which are of interest to biochemists as well as to the preparation of materials. The catalyst system Pd(MeCN)2Cl2/Li2CO3/dioxane allows the direct access to a wide variety of arylated molecules from heteroarenes or alkenes and benzenesulfonyl chlorides. We have developed a method for the direct β-arylation of selenophenes from selenophenes and benzenesulfonyl chlorides. We have also shown that the use of (poly)halogenated benzenesulfonyl chlorides makes it possible to synthesize, by Pd-catalyzed reactions, (poly)halo-substituted arylated heteroarenes, stilbenes or cinnamates

We develop new benzotrithiophene (BTT)-base hole-transporting materials, synthesized by 3-fold C-H/C-Br cross-couplings. We use benzotrithiophene as middle core and 3,4-ethylenedioxythiophene (EDOT) as π-linker. In the end group, we use triphenylamines as donors. The reaction conditions have been optimized by several entries and all HTMs have good yields. Perovskite solar cells based on the new HTM YKP03, which has EDOT as π-linker, achieve 14 % of power conversion efficiency with dopants and get over 13 % of PCE under dopant-free condition. Another HTM YPK05, which has t-butyl groups as function groups, shows great thermal stability and gets over 15 % of PCE in perovskite solar cells. These results indicate that the new HTMs have potential to be used in perovskite solar cells due to the less synthetic steps and avoiding to use hygroscopic dopants, making the elements become more economical and more stable comparing with the normally used HTM Spiro-OMeTAD.

We use 3,4-ethylenedioxythiophene (EDOT), thiophene as middle core and π-linker. In the end groups, we use different donors such as triphenylamine (TPA), carbazole with different alkyl chain to measure their electrochemical, thermal properties, hole mobility and photovoltaic performance. For applications in dye-sensitized solar cells (DSSCs) and perovskite solar cells (PSCs), we demonstrate that two D-A-π-A type new organic sensitizers (CYL-20 and CYL-21) and D-π-D-π-D type hole-transporting materials (KM01-KM07) can be step-economically synthesized by one-pot reactions through sequential C-H arylations. The PCE of perovskite solar cells (PSCs) device achieves 15%. This work aims to provide facile access to high-performance organic sentizers and hole-transporting materials.
