The KRN7000 is a synthetic α-galactosylceramide showing interesting immunostimulating and antitumor properties. The tests showed that the KRN7000 is not directly cytotoxic in vitro against tumor cells, but in vivo and in vitro, it activates the immune system of the organism. Meanwhile, its utilization in the treatment of some types of cancer might be complicated by the in vivo hydrolysis of the C-0 anomeric bond. For this reason, we have been interested in the synthesis of the C-glycosidic analogue of the KRN7000. The strategy proposed by our laboratory is based on an olefin ring closing-metathesis. In order to check the validity of our scheme, and to use some anterior results, we began by a model study in D-glucose series. The enol ether and the allylglycine, our starting materials, were prepared in good conditions. The esterification and metathesis reactions were optimized. Meanwhile, the reduction of the double bond proved to be difficult. Therefore, we modified our retrosynthetic scheme and worked this time in the natural D-galactose series. In our second approach, we were able to improve the preparation of the vinylglycine by the use of microwaves irradiations. The synthesis of the vinyl-C-glycoside was achieved through the syn opening of an epoxide. We then showed that the esterification reaction is complicated by the isomerization of vinylglycine in basic conditions. The use of a selenium derivative allowed us to avoid this problem and obtain the precursor of the metathesis reaction with good yields. The ring closing metathesis did not lead so far to the desired bicyclic compound, but this reaction is still under study in our laboratory

This work was dedicated to the synthesis of original heterocyclic structures starting from Beta-aminoesters obtained via the multicomponent aza-Baylis–Hillman reaction. First of all, we have developed new conditions for the aza-Baylis–Hillman of trimethylsilylethanesulfonamide (SES–NH2), methyl acrylate and an aromatic aldehyde. This methode allowed us the preparation of a large variety of unsaturated Beta-aminoesters. These unsaturated Beta-aminoesters are multifunctional synthons for the preparation of heterocyclic structures. We have prepared five membered ring heterocycles by ring closing metathesis. The different deprotection conditions of the SES group (dehydrodesulfinyaltion and Beta-elimination) allowed the synthesis of pyrroles, pyrrolidines and pyrrolines from the same cyclic precursor. We have also prepared triazolodiazepines by the Huisgen reaction and benzazepines by the Heck reaction under microwave activation

This thesis presents two principles aspects: the first one consists in a regioselective metallation methodologic study of aza-π-deficients systems, and the second one, in the synthesis of highly biological interest scaffolds by organometallic way and / or transition metals couplings. So, in a first chapter, we describe the different results of the reaction between the superbasic complex [n-BuLi / LiDMAE] on π-deficient systems such as 7-azaindole or pyrazine. We also present results of other but close superbasic systems [s-BuLi / LiDMAE], [t-BuLi / LiDMAE], [LDA / LiDMAE], [LTMP / LiDMAE] on a model substrate: 3-chloropyridine. Indeed, this substrate allowed us to study regioselectivity and Basicity / Nucleophilicity ratio aspects. The second part of this thesis describes the synthesis of functionalised and functionalisable bicyclic targets especially containing a nitrogen atom such as pyrano[3,2-b]pyridine and oxepino[3,2-b]pyridine using an organometallic way, followed by transition metal couplings and ring closing metathesis. For this last step, we studied the efficiency of first and second generation Grubbs’ catalysts, comparing each, and optimising for each the yield of product obtained compared to the amount of catalyst introduced. Finally, we envisioned the formation of thieno[3,2-b]pyridines functionalised and functionalisable by regioselective lithiation of 3-methylthiopyridine followed by Sonogashira coupling and electrophilic cyclisation
