The pyrrole ring is present in many natural and biologically active compounds. Therefore, its intensive study in organic synthesis is of a great interest. Thus, the first acid-catalyzed reaction of pyrroles onto nitrones was reported by our team. According to the experimental procedure, either pyrrolic Nbenzylhydroxylamines or 2,2'-bis(pyrrolyl)alkanes were selectively produced. Pyrrolic Nhydroxylamines are important compounds and have been used as starting building blocks for the two methodologies described in this manuscript. Unsymmetrical bis(pyrrolyl)alkanes were obtained efficiently in one step, with high molecular diversity, by the reaction of pyrrolic N-hydroxylamines and various pyrroles. This method also allowed the preparation of symmetrical and unsymmetrical tripyrromethanes. Our results were applied to the preparation of unsymmetrical F-Bodipy® probes. They were obtained, in high yields and for the first time, directly from unsymmetrical 2,2'-bis(pyrrolyl)alkanes. Moreover, an axially chiral F-Bodipy® has been prepared. A-N-Hydroxyamino acids which are N-hydroxylated analogues of a-amino acids have been synthesized. A highly diastereoselective reaction between pyrrole and a suitable cyclic chiral nitrone yielded a pyrrolic N-hydroxylamine. A three-step sequence afforded the expected a-N-hydroxyamino ester in a good yield and a good enantiomeric excess (80%). This method has been applied to other pyrrolic, indolic and furanic heteroaromatics. No a-N-hydroxyamino acids holding these heterocycles in their structures were described. Good overall yields (36-62%) were obtained and good enantiomeric excesses, up to 98%

Heteroaromatics are present in many natural products. Since several years, our group is particularly interested in the reactivity of pyrroles and indoles towards nitrones to give bis(pyrrolyl)alkanes and bis (indolyl)alkanes that could be present in natural compounds such as vibrindole A or in synthetic compounds. These structural patterns are interesting because they could display either anticancer or antibacterial activities. The first part of the present research starts from these previous results. The method developed in the laboratory was extended to new mixed molecules containing either "indole-pyrrole", "indole-furan" or "pyrrole-furan" moieties, in order to test their activities as antibacterial agents. A second part of this manuscript focuses on the development of a "green" preparation of symmetrical 2,2' bis(pyrrolyl)alkanes and 3,3' bis(indolyl) alkanes respectively. Finally, the catalytic enantioselective addition of pyrroles onto several nitrogen-containing electrophiles yielding pyrrolyl methanamines has been developed in the presence of an organic catalyst such as a phosphoric acid with an axial chirality. This method is currently applied to the synthesis of a natural molecule, the (+)-absouline
