the facile and high yield synthesis of a new series of dibenzophenones in the presence of polyphosphoric acid (ppa) together with their cyclization to corresponding moni and dixanthones are described. the aromatic nucleophilic substitution of these new compounds are also studied.
While some sequential electrophilic aromatic substitution reactions, known as tandem/domino/cascade reactions, have been reported for the construction of aromatic single skeletons, one of the most interesting and challenging possibilities remains the one-pot build-up of a complex aromatic molecule from multiple starting components, i.e., ultimately multi-component electrophilic aromatic substit...
