Повний текст джерелаThe projet consists in developing new domino processes involving C-H functionalization as the key steps. The introduction of C-H functionalization in the domino reaction leads to the enhancing significantly the efficiency of the reaction and offers new perspectives in a synthetic point of view. In this context, we have exploited different strategies basing on Heck/C-H functionalization process, difunctinalization of alkenes reactions through oxidative addition and a sequencial intramolecular aminopalladation/C-H functionalization. These methodologies allow rapid constructions of spiroquinolines, spirooxindoles, 3,3'-disubstituted oxindoles, tetracyclic oxindoles and pyrrolo[1,2-a]indoles cores

Повний текст джерелаIn the first part of this manuscript we described dihydrozaphenanthrene fused macrocyclic ring synthesis using a unique domino sequence n-arylation/c-h activation/ c-c bond forming process. This sequence is catalyzed by palladium and is the unique way to rapidly acces to macrocyclic ring via n-arylation with good to excellent yield. During this study, we demonstrated that our substrate acted as ligand for the palladium and favorised the cyclisation. We also determined bond formation order and proved that c-n bond formation preceded c-c bond formation. And we have been able to isolate an intermediate palladium complex, which allowed us to propose a possible mechanism for this transformation. This methodology was successfully applied to 5,6-dihydro-8h-5,7a-diaza-cyclohepta[jk]phenanthrene-4,7-dione synthesis. Then, we demonstrated that copper could be a good catalyst to promote intramolecular n-arylation to produce 1,4-benzodiazepine-2,5-dione. In a second part, we described a new way to synthetize 5-aminooxazole using a passerini modified two component reaction between an aldehyde and an isocyanoacetamide. Those reactions could have been diastereoselectively controlled and applied to rapid synthesis of dipeptide containing norstatine motif

Повний текст джерелаThe present PhD study focuses on the synthesis and characterization of novel perferrocenylated cyclic complexes utilizing cobalt - mediated cyclomerization in combination with C–H bond activation as well as formation of ferrocenylated phosphino-alkyne compounds with iron and cobalt carbonyls. Electrochemical properties and electron-transfer processes between terminal ferrocenyl units in the diverse cyclic compounds are explored in relation to the chemical composition of the building blocks connecting them. Eleven perferrocenylated cyclic compounds were obtained via [2 + 2] and [2 + 2 + 2] cyclomerization of 1,4-diferrocenylbutadiyne FcC≡C–C≡CFc (Fc = Fe(η5-C5H4)(η5-C5H5)) by the reaction with dicarbonylcyclopentadienylcobalt Co(η5-C5H5)(CO)2. They are subdivided into three groups: (i) products of cyclodimerization with additional chain extension, possessing cyclobutadienyl moieties as a central linkage unit (3a,b and 4a,b), (ii) products of cyclodimerization with consecutive CO insertion (6a,b,c and 7), and (iii) products of cyclotrimerization followed by cycle formation via C–H bond activation (5a,b,c). Optimization of the reaction conditions was made in order to maximize the amount of each group of compounds. Furthermore, another part of this research work focuses on diverse reaction patterns of (ferrocenylethynyl)diphenylphosphane with diironnonacarbonyl and dicobaltocta-carbonyl. Six mixed carbonyl and ferrocenyl-functionalized phospinoalkynyl compounds of iron(0) and cobalt(0) were obtained and characterized

ABSTRACT Transition-metal-catalyzed direct conversions of unreactive, less polar CH bonds into numerous organic functional groups by uniting commercially available π-components, which brought a revolution recently in synthetic methodologies for the production of pharmaceuticals, natural products and for opening new routes to organic reactions. Because it can introduce simple conversions, consumes low catalyst loading, inexpensive, readily available starting materials and environmentally friendly conditions. A large variety of metal catalysts, especially rhodium, palladium and ruthenium catalysts are now useful for the efficient catalytic conversion of CH bonds. The uses of rhodium and ruthenium complexes for CH activation via insertion of unsaturated substrates to generate new CC bonds are considerable interest in organic synthesis. In this regard, this thesis describes seven new reactions that focus on the various directing groups with various alkynes and alkenes by rhodium and ruthenium catalyzed CH activations. The CH functionalization reaction affords various functionalized heterocyclic compounds and yields out new five membered and six membered rings. On the other hand carbocyclization, annulation, and insertion reactions of ketone, aldehyde, azo, hydrazine hydrochloride and pyridine containing arenes with simple alkynes and alkenes afforded biologically active indenols, isocoumarins, cinnolinium salts, indoles and amide derivatives in one-pot manner. For better perceptive, I divided this thesis into six chapters. The first four chapters describe about rhodium(III)-catalyzed CH bond activation of aryl ketones, aryl aldehydes, azobenzenes, and aryl hydrazine hydrochlorides with internal alkynes. The fifth chapter describes about rhodium(III)-catalyzed ortho alkenation and cyclization of azobenzenes with alkenes. The final chapter deals with ruthenium-catalyzed amidation of 2-arylpyrindes with isocyanates by CH activation. Chapter 1 describes a regioselective synthesis of indenols by rhodium-catalyzed CH activation and carbocyclization of aryl ketones and alkynes. The catalytic system proceeds via CH activation followed by regioselective insertion of alkynes to give biologically useful, substituted indenols in excellent yields. Chapter 2 deals about a synthesis of highly substituted isocoumarin derivatives from aryl aldehydes and alkynes via C−H activation as a result of rhodium catalyst. This methodology shows in-situ oxidation of aldehydes affords acid and ortho CH activation. This simple method offers an alternative and less expensive way to the synthesis of isocoumarins. Chapter 3 illustrates the rhodium (III)-catalyzed synthesis of cinnolinium salts starting with azobenzenes and alkynes: application to the synthesis of indoles and cinnolines. The reaction path way appears to be the first example employing rhodium catalyzed CH activation and annulation to the synthesis of cinnolinium salts. In addition, the cinnolinium salt products have been successfully applied to the synthesis of three important classes of bioactive compounds and advanced materials namely indole, indoloindole and cinnoline derivatives. Chapter 4 elaborates an efficient regioselective synthesis of indoles from aryl hydrazine hydrochlorides and alkynes via CH activation. This reaction proceeds through the hydrazone group directed selective ortho CH bond activation and insertion of NN bond gave indoles in highly regioselective manner. Chapter 5 reveals a new insertion and aromatization of azobenzenes with alkenes via RhCp*-catalyzed CH activation. The present rhodium catalyzed CH activation reaction is successfully applied to various acrylates and acrylamides to synthesize aminoindole-2-carboxylates and 2-carboxyindoles. Chapter 6 shows a Ru(II)-catalyzed amidation of 2-arylpyridines with isocyanates via CH activation. This method provides an opportunity for the synthesis of various amidated 2-arylpyridines using less expensive ruthenium catalyst under mild reaction condition.
