The nucleosidic bond of C-nucleosides are much more stable than N-nucleosides, which allows potential applications of C-nucleosides in medi-cinal chemistry and chemical biology. Some of the naturally occurring C-nucleosides possess a wide variety of biological activities. We are particu-larly interested in the synthesis of pseudouridine and 2’-deoxypseudouridine. In this thesis, we employed Heck-type coupling reactions to form C-C bonds between the anomeric carbon of 1, 2-unhydrous sugar derivatives and aryl iodides or iodo-heterocycles. Instead of utilizing toxic and expensive AsPh3 as the ligand, tour study has showed that the use of bidentate ligands for Heck-type coupling reactions were highly regio- and stereoselective. The methodology is applicable to the synthesis of 2’-deoxypseudouridine and pseudouridine.

This thesis is composed of two parts. The first part is the palladium/cationic 2,2’-bipyridyl system catalyzed Mizoroki–Heck type reaction of arylboronic acids and diethyl phosphonates in water under air and the second part is the three component coupling reaction for the formation of propargyl amines catalyzed by ZnO supported CuO nanoparticle. We combine PdCl2(NH3)2 with cationic 2,2’-bipyridyl ligand as a catalytic system to catalyzed the coupling of arylboronic acids with diethyl vinylphosphonates or diethyl allylphosphonates resulting in the formation of corresponding Mizoroki–Heck type products. The reaction is high-yielding and high selectivity and can be performed in water under air, rendering it an environmentally-benign procedure. On the other hand, a ZnO supported CuO nanoparticle catalyst is prepared by simple procedure and can be applied as a heterogeneous catalyst for the coupling of alkyne, aldehyde, and amine leading to the formation of propargyl amine. The CuO/ZnO catalyst shows highly efficient for this three component coupling and the catalyst loading can be reduce to 0.01 mol% by up the scale to 70 mmol. After reaction, the catalyst can be recovered by simple centrifugation and reused for several times with only slight loss of it activity.

Five highly fluorinated bipyridine derivatives, (4,4’-bis(RfCH2OCH2)-2,2’-bpy), {Rf = n-C8F17(1a), n-C9F19(1b), n-C10F21(1c), n-C11F23(1d)} and (4,4’-bis(RfCH2CH2OCH2)-2,2’-bpy), {Rf = n-C8F17(1e)} have been synthesized using 4,4’-bis(bromomethylene)¬-2,2′-bpy and fluorinated alkoxides. The ligands have high fluorine contents and also high fluorophilicity, the partition ratio being 1:1.07, 1:1.04, 42:1, 70:1 and 6.56:1 for the FC 77/CH2Cl2 system, respectively. The reactions of ligands 1a-e with [Pd(CH3CN)2Cl2] result in new palladium complexes [PdCl2(4,4’-bis-(RfCH2OCH2)-2,2’-bpy)], where{Rf = n-C8F17(2a), n-C9F19(2b), n-C10F21(2c), n-C11F23(2d)}, and [PdCl2(4,4’-bis-(RfCH2CH2OCH2)-2,2’-bpy)], where{Rf = n-C8F17(2e)} respectively. Insoluble in organic solvents at room temp, the novel Pd complexes 2a-e dissolves in fluorinated solvents only, for instance FC77, which is mainly C8F18. The Pd complexes 2a-e have been successfully tested as the generic and recyclable catalysts in Heck-type and Suzuki-type reactions under the fluorous biphasic and thermomorphic conditions.

Several new secondary phosphine oxides (SPOs) containing indole moiety were prepared. These new compounds are air- and moisture-stable preligands and advantageous for the purpose of storage. The structures of pallidium complexes might be stabilized by these SPOs. Pallidium complexes (3b & 4b) were obtained from the reactions of PdX2 (X = Cl, Br) with ligand (2b) and structures were determined by single-crystal X-ray diffraction methods. Applications of these SPO ligands (2a-2c) in palladium-catalyzed Heck-type Catellani reactions exhibited acceptable efficiencies. A extended mechanism was propsed to count the formations of all the organic products.

Повний текст джерелаOs flavonoides são uma ampla família de metabolitos secundários ubíquos no Reino Vegetal. Estes compostos orgânicos de ocorrência natural têm sido alvo de grande interesse de estudo devido ao seu reconhecido potencial farmacológico. Entre as suas múltiplas propriedades biológicas destacam-se as atividades antioxidante e anti-inflamatória tanto de derivados naturais como de derivados sintéticos. No universo dos compostos heterocíclicos de oxigénio, as flavonas (2- arilcromonas) assumem especial importância devido à sua abundância, diversidade e amplo leque de propriedades farmacológicas às quais estão associadas. Alguns derivados halogenados desta estrutura molecular tão privilegiada provaram possuir atividades biológicas aprimoradas, sendo ainda valiosos intermediários na síntese de outros compostos orgânicos, nomeadamente mediante reações de acoplamento cruzado. Apesar de existirem vários métodos de síntese de haloflavonas, muito permanece ainda por desvendar relativamente ao controlo da regiosseletividade na halogenação. Parte do trabalho descrito nesta tese centrou-se na síntese de compostos do tipo flavonoide. Foram desenvolvidas novas rotas de síntese para a obtenção de novas flavonas com diferentes padrões de substituição: flavonas metoxiladas, hidroxiladas e cloradas em várias posições do seu esqueleto carbonado. Foi efetuada a avaliação biológica destes compostos assim como o estudo da relação estrutura–atividade (SAR), tendo alguns derivados exibido atividades antioxidante e anti-inflamatória muito satisfatórias e comprovado potencial no tratamento da diabetes mellitus tipo 2. Foram ainda estudadas a síntese estereoesseletiva de novos derivados do tipo (E,E)-aminoaurona e a preparação de novos análogos de iodofeniloxibenzaldeídos e iodoxantonas. Na natureza os compostos fenólicos encontram-se frequentemente associados a unidades de hidratos de carbono. No âmbito da química medicinal, o reconhecido e crescente interesse nos compostos fenólicos C-glicosilados advém da combinação de várias caraterísticas vantajosas a estes inerentes: a distinta estabilidade hidrolítica da ligação C-glicosídica, o elevado caráter hidrofílico proporcionado pelas unidades de açúcar e ainda tudo isto associado à reconhecida importância biológica dos compostos fenólicos. Nesta dissertação é também descrito o estudo efetuado no âmbito da síntese de novos compostos fenólicos substituídos por unidades de açúcar mediante ligações C–C. Para tal, foram preparados derivados vinilados de açúcar (do tipo furanose e piranose) e também derivados halofenólicos do tipo fenoxibenzaldeído, xantona, cromona, (E)-2-estirilcromona e (E,E)- aminoaurona. Tendo como estratégia-chave a reação de acoplamento cruzado de Heck, foi possível a síntese de vários novos derivados fenólicos contendo unidades de açúcar. A elucidação estrutural inequívoca de todos os compostos sintetizados foi efetuada através da espetroscopia de ressonância magnética nuclear 1D e 2D e sustentada pela análise de espetrometria de massa, análise elementar ou espetrometria de massa de alta resolução.

A series of 1,2-diaminocyclohexane and o-phenylenediamine derivatives as diamine ligands (3a-3h) were prepared, and further reactions led to the formation of secondary phosphine oxides (SPOs, 4a-4c).The molecular structures of 4c and complexes 3a_Pd, 3b_Pd, 3c_Pd, 3d_Cu were determined by single crystal X-ray diffraction methods. After screening of the ligands, diamines showed better coordinating capacities toward the palladium salt. These ligands can stabilize the palladium complexes during the catalytic reactions. Catalysis of the Suzuki-Miyaura coupling reactions with 3a for the aryl bromides showed good yields, nevertheless, lower reactivities were observed for aryl chlorides. In addition, 3d was employed in the Heck reaction as ligand. It exhibited a good tolerance of functional groups for the aryl bromides.
