Summary

Coumarins have been prepared from ethyl-β-resorcylate and resacetophenone by condensing them with cylic β-ketonic esters like ethyl cyclohexanone-2-carboxylate, ethyl cyclo-pentanone-2-carboxylate and ethyl-4-methyl-cyclopentanone-2-carboxylate in presence of 73 per cent. sulphurie acid, phosphorous oxychloride and anhydrous aluminium chloride as condensing agents. Only 7-hydroxy coumarins were obtained in the case of methyl β-resorcylate, while resacetophenone gave 7-hydroxy-coumarins in presence of phosphorous oxychloride, but 5-hydroxy coumarins with aluminium chloride.
