Full textThis work focuses on the thermosetting materials area with applications in coatings or encapsulates for microelectronic devices and it seeks to obtain materials with better durability that after their working life, could be degraded and let the recuperation of the electronic material, which means a great advantage for the environment. The strategy followed has been the copolymerization of diglycidylether of bisphenol A (DGEBA) with mono--lactones and condensed bis--lactones using several rare earth triflates and BF3·MEA as cationic initiators and several tertiary amines as anionic iniciators. This strategy lets the introduction of ester linkages, thermal and chemically cleavable and at the same time the reduction of the shrinkage which is produced during the curing process. The incorporation of aliphatic chains, that come from lactones, between cross-linking points increases the flexibility of the polymeric network and decreases the fragility of the material. The improvement of the mechanical properties also was studied adding layered montmorillonites.

Full textThe development of new synthetic pathway leading to enantiopure compounds with significant structural diversity is an ongoing challenge in many fields of chemistry. The efficiency of these processes has to be evaluated, not only in term of quantitative criteria, such as yields and/or optical purities of obtained compounds, but also by analyzing the environmental impact of the different processes involved. In this work, we sought to develop new methodologies for the synthesis of polyfunctional chiral γ-lactones. The 5-hydroxyfuran-2(5H)-one, a bio-based molecule, was used as a platform to the construction of the γ-lactone ring. In the first part of our work, a variety of chiral γ-lactone displaying a great structural diversity were obtained by a one-pot sequential reaction. First, a step of enantioselective organocatalysis allowed the activation for the transfer of boronic acids on the hydroxyfuran-2(5H)-one; then the chiral adduct formed was engaged in a Passerini reaction leading to the construction of the lactone ring. In a second part, our efforts focused then on the development of catalytic asymmetric alkylation reactions leading to the construction of γ-lactones bearing an all-carbon quaternary stereocenter. Asymmetric allylic reactions were carried out with a very good control of the selectivity of the reaction by the use of palladium and iridium complexes catalysts. Theses lactones bearing an [1,5]-diene scaffold were then engaged in a sigmatropic [3,3] reaction opening a path for a new approach to the functionalization of aromatic heterocycles. Finally, the use of organic enantioselective catalysis was envisioned for the creation of all-quaternary stereocenters
