Abstract
Anthrons are important precursors for a variety of antitumor and antibiotic drugs. This work is towards the synthesis of two bisanthrons 6 and 10.These bisanthrons are synthesised via the corresponding bislactones 4 and 8 and the dicarboxylic acids 5 and 9 which respectively are formed through the cleavage of the above bislactones. We have taken advantage of the "biscyclization" method in the simultanious cyclization of the above dicarboxylic acids for the synthesis of corresponding bisanthrons.
