Abstract
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.
Claims11
