1. (R)-Phenylglycinol-derived oxazolopiperidone lactams can be converted to enantiopure open-chain amino ester scaffolds by alkaline hydrolysis of the N-Boc 2-piperidones resulting from the reductive cleavage of the ...
Although sygma-aryl and sygma-vinylpalladium(II) complexes are commonly used as electrophiles in C—C bond forming reactions, recent research has demonstrated that the same palladium intermediates can also react with ...
En la present tesi doctoral s’ha desenvolupat una estratègia per obtenir els esquelets dels quatre alcaloides licopodi representatius a partir d’un mateix intermedi sintètic comú 1, de manera semblant al procés que té lloc ...
The first objective of this Thesis was the study of the preparation of octhydro-1H-cyclopenta[b]pyridines and octahydro-1H-indoles, through the synthesis of (R)-phenylglycinol derived tricyclic lactams. Following the ...
This doctoral thesis consists in two main parts. The first part focus in the study of methodology development in order to bring modularity and diversification to compounds studied within the research group. It consists ...
Sphingolipids (SLs) are essential structural and signaling molecules of eukaryotic cells. An important group of SLs metabolites are those showing a phosphate group at the C1‒ OH. Among them, sphingosine‒1‒phosphate (S1P) ...
This PhD Thesis pursues the development of novel anti-Alzheimer and antiprotozoal drug candidates upon exploitation of three different novel approaches: Multitarget therapies, Drug repurposing, and Validation of a novel ...
En esta Tesis doctoral, se ha puesto a punto una ruta sintética para acceder de manera rápida y eficaz, a compuestos policíclicos tipo “cinturón” que contienen dos dobles enlaces C=C casi paralelos y próximos en el espacio. ...
Existe una correlación positiva entre el incremento de la esperanza de vida y el aumento de las enfermedades crónicas. Se ha establecido que el envejecimiento es el principal factor de riesgo en la aparición de trastornos ...
The manuscript of this Doctoral Thesis has been divided into five main parts: a general introduction into the calyciphylline A-type alkaloids followed by three research chapters and conclude by a review about the radical ...
Durante este trabajo de tesis doctoral se ha demostrado que las cloroacetamidas son intermedios de gran utilidad para la síntesis de heterociclos nitrogenados a través de procesos radicalarios o no radicalarios. En este ...
L’objectiu de la present tesi doctoral consisteix en desenvolupar molècules policícliques de baix pes molecular que tinguin com a diana tres canals iònics específics: la viroporina A/M2 del virus de la grip, el receptor ...
Epigenetic changes are currently recognized as part of the aging process and have been implicated in many age-related chronic diseases such as Alzheimer’s disease (AD). The term epigenetics includes a variety of processes ...
Sphingolipids (SLs) are components of eukaryotic cell membranes that in the last 30 years have shown not only a structural role but also be involved in signaling processes and cellular responses. Therefore, the development ...
En les últimes dècades, l’increment del consum de sucres, especialment de fructosa, s’ha associat al desenvolupament de la obesitat i d’alteracions metabòliques com ara diabetis, hipertensió i malalties cardiovasculars. ...
Alzheimer’s disease (AD) is the main neurodegenerative disorder and one of the most important health-care problems worldwide, because of its high prevalence and personal and economic impact. To aggravate this situation, ...
The present thesis is included in the area of Nanomedicine and supramolecular chemistry, focused on the design and preparation of different nano and microtools for delivery, therapy and sensing. Initially, the synthesis ...
1. It was observed that the interaction of imines and isocyanides in the presence of a Lewis acid can lead to a variety of scaffolds including α-aminoamides, α-aminoamidines, indoles and diiminoazetidines. The reaction ...
Chiral amino alcohol derived lactams are a valuable scaffold for the enantioselective synthesis of alkaloids. In the present thesis the potential of this methodology was expanded and to demonstrate the synthetic utility ...
La población mundial está envejeciendo, la mayoría de países del mundo están experimentando un aumento en el número y la proporción de personas mayores. Los últimos datos publicados de la ONU en 2017 informan que se espera ...
