Patent

CA 2208148

Strapped porphyrins and electron-deficient porphyrins are provided, as well as processes and intermediates for their preparation. In certain embodiments, such compounds are prepared by nucleophilic displacement of leaving groups from methylpyrroles. In other embodiments, such compounds are prepared by condensing pyrrole derivatives and removing water thus formed from the resulting reaction mixture.

Cette invention concerne des porphyrines liées et des porphyrines électron-déficientes, ainsi que les procédés de préparation et les produits intermédiaires obtenus. Dans certains modes de réalisation, les composés sont préparés par le déplacement nucléophile de groupes partants de méthylpyrroles. Dans d'autres modes de réalisation, ces composés sont préparés par la condensation de dérivés de pyrroles, ce qui permet de séparer l'eau issue du mélange réactionnel ainsi obtenu.
