Testo completoPeptides and proteins are amongst the essential molecules in the everyday life. Consequently, they are widely investigated and used in several synthetic and natural-derived materials covering a broad range of applications. Hence, mastering their production, especially by chemical synthesis, is of utmost importance.Our group has proposed an original procedure for the formation of amides on the basis of a novel mode of activation (“inverse activation” of AA through the amine function) affording the synthesis of several dipeptides. Nonetheless, this methodology presents some main drawbacks such as the long time to complete the reaction.This PhD thesis work focuses on improving this methodology to synthesise peptide targets and to be able to extend the methodology to the synthesis of “general” (no-amino acids substrates) amides. To accomplish our aim, we examined the different parameters of the peptide coupling such as the solvent, the concentration, the activating reagent, the additives and the time of the reaction. For instance, in terms of reaction kinetics we were delighted to observe that the reaction could take place in only 30 minutes instead of 20 hours using microwave irradiation. Moreover, we found that the additives used for the reaction (CuBr2/HOBt 10 mol% each) could be replaced by a catalytic amount of trifluoroacetic acid in a more diluted solution to give dipeptides in good yield (in the absence of a transition metal). Then, we focus our attention on the synthesis of general amides. Once the reaction conditions were optimised, we explored the scope of the substrate obtaining the desired products in good yield showing the versatility of this methodology.In parallel, we realised another project on the ring-expansion of the vinyl aziridines in order to afford the formation of 3-pyrrolines, interesting building blocks in organic synthesis

Testo completoIn recent years, industrial and academic researches have experienced unprecedented changes related to the concept of sustainable development. Health and environment new requirements have prompted chemists to develop chemical products and processes that reduce or eliminate hazardous substances. The research work described in this thesis is focused on the development of new reducing systems using hydrosiloxanes as substitutes for aluminum and boron hydrides. In order to achieve this goal, reducing systems combining 1,1,3,3-tetramethyldisiloxane (TMDS) or polymethylhydrosiloxane (PMHS) with titanium or vanadium complexes have been developed for the reduction of amides and nitriles. The nature of both the association “hydrosiloxane – metal” as well as the studied substrate played an important role on the performance and the selectivity of the reaction. On the one hand, selective reductions of amides (tertiary and secondary) and nitriles to aldehydes were carried out respectively in the presence of titanium(IV) tetraisopropoxide and vanadium(V) triisopropoxide oxide. On the other hand, reductions of amides (primary) and nitriles afforded the corresponding primary amines in the presence of titanium(IV) tetraisopropoxide. Finally, these systems have been applied for the synthesis of saturated N-heterocycles. Reduction of dinitrile compounds led, in one step, to piperidine, pyrrolidine and azetidine derivatives through an intramolecular reductive alkylation reaction
