SYNTHESIS OF NEW PYRANOCOUMARINS

As a result of condensing 5,7-dihydroxy-4-methylcoumarin with dimethyl acetal-3-methylbuten-2-al, 4-methyl-5-hydroxyseseline, 4-methyldipetalolactone and 5-hydroxy-4,10,10-trimethyl-2H,8H-benzodipyran-2-one have been obtained.Condensation of 5,7-hydroxycoumarin with this acetal leads to 5-hydroxyseseline, dipetalolactone and 5-hydroxy-10,10-dimethyl-2H,8H-benzodipyran-2-one
