1. In vivo chemotherapeutic insight of a novel isocoumarin (3-hexyl-5,7-dimethoxy-isochromen-1-one): Genotoxicity, cell death induction, leukometry and phagocytic evaluation
Abstract Chemotherapy is one of the major approaches for the treatment of cancer. Therefore, the development of new chemotherapy drugs is an important aspect of medicinal chemistry. Chemotherapeutic agents include isocoumarins, which are privileged structures with potential antitumoral activity. Herein, a new 3-substituted isocoumarin was synthesized from 2-

2. Reagentes organometálicos: preparação e reatividade de compostos orgânicos de telúrio / Organometallic reagents: preparation and reactivity of organic compounds of tellurium
Nesta tese foram desenvolvidas metodologias sintéticas para a preparação de compostos orgânicos de telúrio empregando reagentes organometálicos. Primeiramente, foi estudada a abertura tipo SN2 de lactonas, por organoiltelurolatos de lítio ou magnésio para obtenção dos respectivos ácidos telurocarboxílicos. Os organoiltelurolatos foram preparados

3. Desenvolvimento e aplicação de eletrodos à base de nanotubos de carbono / DEVELOPMENT AND APPLICATION OF ELECTRODE BASE ON CARBON NANOTUBES
The electrodes based on carbon nanotubes (CNTs) were prepared in the form of paste of CNTs/Graphite and film on glassy carbon electrode. These electrodes were electrochemically characterized by their response in potassium ferricyanide and hydroquinone. Considering the obtained results, the electrode in the form of paste was selected for analytical applicatio

4. Arilação seletiva de ânions heterocíclicos ambidentados por sais de difenil iodônio / Seletive arylation of ambident heterocycle anions by diphenyl iodonium salts
A arilação seletiva de compostos orgânicos confere-lhes propriedades com amplas aplicações: em compostos de atividade biológica, inibidora da protease do vírus HIV-1, e de interesse como agroquímicos ou na engenharia de materiais. Em razão disso, novos métodos e reagentes tem sido desenvolvidos com essa finalidade. Sabe-se que a N-arilação de vá

5. Total synthesis of (+)-crocacins "C" and"D": synthesis of the 6,6-spiroketals / Sintese total das (+)-crocacinas C e D : sintese dos fragmentos 6,6-espirocetal das espirofunginas A e B
Chapter 1 describes the asymmetric total synthesis of (+)-crocacin C (1.3) and D (1.4). The convergent total synthesis of (1.3) relies on the use of a regio- and stereoselective epoxidation of an allylic alcohol with m-CPBA followed by epoxide opening with Me2CuCNLi2 and a Stille cross-coupling between (E)-vinyl stannane (1.111) and (E)-vinyl iodide (+)-(1.1

6. Sintese e reatividade de complexos cis-bis(alquinila)platina(II) e clusters de ferro-platina
This thesis describes the results of the synthesis, characterisation and reactivity of cis-bis(alkynyl)platinum(II) complexes and iron-platinum clusters. The preparations of cis-bis(alkynyl)platinum(II) complexes were performed using terminal alkynes and [Pt(cod)Cl2] in reactions catalysed by copper(I) iodide. Posterior cod ligand substitution reactions gave

7. Estudo da reação de Simmons-Smith : obtenção vinilciclopropanos substituidos de interesse industrial
Of the procedures described in the literature, that of Rawson e Harrison gives under standard conditions the best results for the cyclopropanation of cyclohexene. We found that the noble metal salt used to activate the metallic zinc has a more important role than to clean its surface, as the yield of the reaction is strongly influenced by the anion. In the p
