Estudos sobre a aplicação do pentacloreto de nióbio na síntese de derivados de 4-aril-3,4-di- hidrocumarinas

Coumarin is a natural active compound that can be found in many plants. The coumarins have many properties such as bronchodilator, anti-inflammatory, antioxidant, anticoagulant, antibiotics, immunomodulatory, antimicrobial and antiviral, thus, they are widely used in medical applications. More recently the coumarin derivatives have attracted the interest of many research groups in the field of new materials, for example the possibility of their use as sensitizers in dye-sensitized solar cells (DSSC) and lasers. The MCRs are defined as a process in which three or more reactants are combined in the same reaction pot, resulting in products with good structural complexity a single step, in addition to economy of atoms and selectivity and is a very important feature in modern synthetic methodology. In this work we investigated the use of niobium pentachloride as catalyst of the multicomponent reactions between phenolic derivatives, various aromatic aldehydes and β-diester derivatives in the synthesis of 4-aryl-3,4-dihydrocoumarin derivatives. The reactions were carried out at room temperature, under inert atmosphere (N2), using dichloromethane anhydrous (CH2 Cl2) as solvent, with a reaction time of most 120 hours. The products were isolated by column chromatography on silica gel and submitted to spectrometric and spectroscopic analysis. The results show that NbCl5 is an excellent agent for promoting the synthesis of 4-aryl-3,4-dihydrocoumarin derivatives through multicomponent reactions, obtaining yields varying from 45 to 95%

Gestos de subjetivação: as dificuldades para realizar uma história do corpo e da sexualidade

The article presents, from the Analysis of French Discourse, different gestures of reading and interpretation of the body and sexuality at various times in history. It demonstrates that such gestures reading are the fruit of experience that each society sets about their cultural values and norms in each period, both in the first civilizations to the economy of sex for birth control and the survival of the group and in the Medieval Christianity control of sex in the fight against sin. Each society according to Michel Foucault, establishes a system of knowledge and power to order and classify the type of body and citizen you desire, like the city of Sparta with its regime of knowledge and training of the soldier and in Athens with the democratic regime in the formation of the political, or contemporary society in the formation of the body of perfect proportions that meet the stipulations of the market.
