    • Abstract

       

      A fresh method for building up furan rings on to coumarin and flavone compounds has been studied. Starting with umbelliferone, 4-methyl-umbelliferone and 3-methoxy-7-hydroxy-flavone the corresponding angular α-methyl-dihydrofuran derivatives have been obtained. The 8-allyl compounds are first prepared and these are subjected successively to treatment with mercuric chloride, iodine in potassium iodide solution and sodium in alcohol.
