This thesis describes an approach to case-based reasoning based on hierarchical classification. A case consists of a problem and a solution to this problem. Case-based reasoning consists in exploiting a case base in order to solve a problem called the target problem. In the framework of this thesis, such a reasoning takes two main steps: retrieval and adaptation. Retrieval consists in searching the case base for a case similar to the target problem. Adaptation uses the retrieved case in order to build up a solution to the target problem. The case base is organised in a hierarchy. Retrieval is performed by a "strong" classification step followed -if needed- by a "smooth" classification step. Strong classification consists in searching in the case base hierarchy for a case more general than the target problem, i. E. A generic case the solution of which can be specialised into a solution of the target problem. If this search succeeds, the adaptation of such a case can be performed by specialised of the generic case found. Otherwise, the role of smooth classification is to make sorne modifications on the cases of the hierarchy and on the target problem within the objective of having one of these modified cases more general than the modified target problem. Then the adaptation step takes these modifications into account. The application of this thesis takes place in the domain of planning in organic synthesis. In this application, a problem is given by a molecule and a solution is a synthesis plan, Le. The description of a chemical method for building up a molecule

This manuscript presents a study of cycloisomerization reactions, in accordance with the principles of green chemistry, based on the electrophilic activation of alkynes in the presence of achiral and chiral Brønsted acids via the formation of vinyl cation intermediates and the attack of the latter by carbon nucleophiles. The use of a catalytic amount of Brønsted acid with 2-alkynylbiaryl substrates delivered phenanthrene derivatives in good to excellent yields under mild reaction conditions. High catalytic activities, along with differences of chemo- and regioselectivity were observed when comparing to carbophilic metallic Lewis acid catalysts.The use of a directing group substituting the alkyne function, the 2-naphtholyle moiety, resulted in increased basicity of the alkyne, increased regioselectivity of the protonation step and the creation of hydrogen bonding with the catalyst, paving the way for the development of an asymmetric version of cycloisomerization reactions. In the presence of chiral Brønsted acids, such as N-triflylphosphoramides, the enantioselective synthesis of atropisomeric phenanthrenes was achieved with excellent yields and good enantiomeric excesses. An intermolecular reaction of hydroarylation of alkynes in the presence of the same catalysts delivered atropisomeric alkenes in excellent yields and enantioselectivities.The use of a directing group on the alkyne also allowed for the first time the development of Brønsted acid-catalyzed enyne cycloisomerization reactions involving the initial, selective protonation of the alkyne function. A variety of polycyclic scaffolds were obtained by this methodology with high yields and moderate enantioselectivities.The cycloisomerization catalytic reaction is known to chemists as a model reaction respecting several principles of green chemistry such as atomic economy, waste limitation and the principle of catalysis.However, no quantitative evidence is provided by chemists to promote the sustainability of the methodologies developed in their laboratories. Several monocriteria parameters and multi-criteria methods have been developed to try to address this environmental quantification issue. However, the interest in developing new catalytic systems should be associated with the development of more environmentally efficient processes in addition to knowing if it is more chemically efficient.Life cycle assessment (LCA) is the standardized reference method for quantifying the environmental impacts (e. g. climate change, toxicity, resource use) of a product over its life cycle. LCA has already been applied to green chemistry developments to compare the durability of chemical reactions, or for eco-design applications. However, it is not trivial to use LCA at the laboratory scale because it requires (i) data that are difficult for the chemist to access (ii) additional modeling steps to estimate potential impacts at the industrial scale (iii) requires the expertise of a LCA practitioner.
