Abstract:
The application of nitrile oxide/isoxazoline chemistry towards the synthesis of higher sugars (monosaccharides containing seven or more contiguous carbon atoms) has been investigated. This convergent approach, involving the cycloaddition of sugar derived alkene and nitrile oxide fragments and subsequent manipulation of the resulting isoxazoline, has much of the product stereochemistry preselected. Three ω-unsaturated monosaccharides were chosen for study: the D-glucose-derived six carbon unit (<i>94</i>), its C-3 epimer (<i>102</i>) and a seven carbon alkene, (<i>97</i>), prepared from D-galac

Abstract:
A route to carbon-linked disaccharides (two monosaccharide units linked by a carbon bridge rather than a glycosidic oxygen) employing nitrile oxide/isoxazoline chemistry has been investigated. This convergent approach is based on cycloaddition of sugar-derived alkene and nitrile oxide fragments, followed by ring cleavage and functional group manipulation of the resulting 2-isoxazoline. Careful selection of the nitrile oxide and alkene fragments defines much of the stereochemistry of the products.

Abstract:
Cytidine triphosphate synthetase (CTPS), a glutamine amidotransferase (GAT) responsible for the de novo synthesis of CTP, was recently suggested as a potential drug target for the treatment of Human African Trypanosomiasis, a parasitic disease caused by Trypanosoma brucei. Acivicin, a natural antitumor antibiotic, is a well-known inhibitor of enzymes belonging to the GAT family. Its CTPS inhibitory activity has been related to the observed trypanocidal activity in bloodstream T. brucei cell cultures. The aim of this project was the design and synthesis of Acivicin analogues characterized by

Abstract:
Neglected diseases reach millions of people around the world. Among these are Chagas disease and Leishmaniasis. Chagas disease is caused by a protozoan, the Trypanosoma cruzi and its main form of transmission is through the faeces of the insect commonly known as barber. Leishmaniasis can be caused by more than 20 types of parasites of the genus Leishmania and there are 3 types of the disease, Cutaneous Leishmaniasis, Cutaneous-Mucous or Tegumentary Leishmaniasis, and Visceral Leishmaniasis. For the treatment of these diseases numerous problems exist, such as the large amount of side effects, l

Abstract:
A new approach to fulminic acid cycloadditions has been developed. At reduced temperatures, fulminic acid is generated in situ and undergoes 1, 3-diploar cycloaddition reactions with dipolarophiles to form isoxazolines and/or its dimers. This procedure represents a novel, safe general method for the one-step generation of fulminic acid, which complements existing potentially explosive protocols.

As reações de cicloadição 1,3-dipolar são uma poderosa ferramenta para a síntese de uma variedade de anéis heterocíclicos de cinco membros. A cicloadição de óxidos de nitrila à olefinas, em particular, é de considerável interesse para a obtenção de isoxazolinas, que são intermediários versáteis na síntese de produtos naturais e de materiais com potencial aplicação como cristais líquidos. A Teoria do Funcional da Densidade foi utilizada para estudar o mecanismo da reação cicloadição [3+2] 1,3-dipolar que ocorre, inicialmente, entre o óxido de benzonitrila e o ácido vinilacético.
