Le N-hydroxytétraphénylphtalimide (NHTPPI) présente une activité catalytique sensiblement supérieure à celle du N-hydroxyphtalimide (NHPI) dans l'oxydation aérobie de substrats organiques. Deux nouvelles voies d'accès à des analogues fonctionnalisés du NHTPPI ont été étudiées. La première implique une réaction de Diels-Alder entre des oxydes ou dioxydes de thiophènes polyaromatiques et le maléimide ou l'anhydride maléique. De nombreuses limitations rendent cette approche difficilement généralisable. Dans la deuxième voie, l'étape clé est une cycloaddition entre des tétracyclones ou des acécyclones et le 2-bromomaléimide qui conduit directement au motif phtalimide par décarbonylation et déshydrobromation de l'adduit de Diels-Alder. Cette mét...
