The methyl ether of karanjic acid has been converted into 5-ω-methox acetyl-4-methoxycoumarone which is found to be identical with the meth ether of the ketone obtained by the hydrolysis of karanjin with alka Following a similar procedure 5-ω-methoxyacetyl-4-hydroxycoumaroi has been synthesised from karanjic acid and this yields karanjin when col densed with benzoic anhydride and sodium benzoate. Thus all the stages the complete synthesis of karanjin have been accomplished.
