dcterms.abstractEn partant de la (S)-4-hydroxyméthyl-butyrolactone, commerciale et largement utilisée, la synthèse stéréocontrôlée de composés reliés de 1,2-méthano-1-substituted-4-hydroxymethyl-tétrahydrofuranes a été réalisée en utilisant une stratégie de cyclopropanation publiée par le groupe du Professeur Hanessian. Dans le cadre d'une collaboration avec le SGC de Toronto, certains 1,2-méthano-1,4-tétrahydrofuranes substitués ont été testés contre un panel d'histone-méthyl-transférases. Dans le second chapitre, une courte synthèse de trois analogues nucléosidiques contraints, 1´,2´-méthano-2´,3´-désoxypseudouridine (C-nucléoside), le 1´,2´-méthano-2´,3´-désoxyuridine et le 1´,2´-méthano-2´,3´-désoxycytidine et leur pro-médicament aryloxyphosphoramidate correspondant a été réalisée en utilisant la stratégie de cyclopropanation. Les tests biologiques de ces analogues modifiés en tant qu'agents antiviraux ont été effectués par les laboratoires Merck à Rahway, NY. USA. Aucun des composés n'a montré d'activité contre le VIH, le VRS et l'Herpès.fr
dcterms.abstractStarting from the commercially available and widely used (S)-4-hydroxymethyl- butyrolactone, the stereocontrolled synthesis of bicyclic 1,2-methano-1-subtituted-4-hydroxymethyl-tetrahydrofurans was accomplished using a tin-mediated cyclopropanation strategy reported by the Hanessian group. As a part of a collaboration with the SGC of Toronto, some of the 1,2-methano-1-substituted-4-hydroxymethyl-tetrahydrofurans were tested against a panel of histone methyltransferases. In the second chapter, a short synthesis of three constrained nucleosides analogues, 1´,2´-methano-2´,3´-dideoxypseudouridine (C-nucleoside); 1´,2´-methano-2´,3´-dideoxyuridine and 1´,2´-methano-2´,3´-dideoxycytidine and their corresponding aryloxyphosphoramidate-prodrugs was achieved using the tin-mediated cyclopropanation strategy. The biological testing of the modified analogues as antiviral agents was performed by Merck in Rahway, NY, USA. None of the compounds showed activity against HIV, RSV and Herpes.fr
