Desenvolvimento de Metodologia Sintética Para a Síntese de Quinolonas Contendo Substituintes Triazólicos
| Posted on: 12 fev. 2007Within the framework of research related to the chemistry of new substituted 4-oxoquinoline derivatives we decided to investigate an appropriate methodology for the synthesis of new 4-oxo-quinoline derivatives, containing ... -
Estudo das sínteses de orto-quinona-metídeos e orto-diazo-naftoquinonas
| Posted on: 19 mar. 2003Several synthetic routes for preparing o-quinone methides were studied. By using an aldolic condensation route with β-lapachone (4a), it was possible to obtain the following o-quinone methides having electron withdrawing ... -
ESTUDOS VISANDO A SÍNTESE DE DIAMINAS DERIVADAS DE PINENOS COM POTENCIAIS ATIVIDADES NOS RECEPTORES NICOTÍNICOS DO SISTEMA NERVOSO CENTRAL
| Posted on: 05 out. 2006In this work are described the attempts of generating stereoselective syntheses of the 1,2,3-triazolic and piridine amines Ia,b-IVa,b, which constitutes in new analogous of the nicotine with potential activities as agonists ... -
SÍNTESE DE DERIVADOS DO FURFURAL E DA δ-GLUCONOLACTONA COM POTENCIAL ATIVIDADE ANTI-INCRUSTANTE
| Posted on: 11 mai. 2010Currently, there is a great interest in the research substances for potential inhibition of scale, since depositions of sulfates and carbonates are .causing of many damages to the system of production and decrease of the ... -
Síntese de novos derivados 1h-pirazolo[3,4-b]piridina fosforamidatos candidatos a atividade antileishmania
| Posted on: 23 fev. 2011The leishmaniases are zoonoses considered initially broadcast essentially wild, being limited to rural areas and small urban areas. Currently shows changes in transmission patterns due to the socio-environmental changes ... -
