Thermal treatment of homophthalic anhydrides (1 and 2) with various dienophiles (3-12) caused cycloaddition with spontaneous extrusion of carbon dioxide to give the corresponding linearly condensed peri-hydroxy aromatic compounds (13-23) in considerable yields.A possible mechanism for these reactions is proposed.Keywords - cycloaddition; homophthalic anhydride; thermal reaction; carbon dioxide extrusion; regiocontrolled reaction; linearly condensed phenolic compound; peri-hydroxy aromatic compound; tetracyclic compound
