The thermal Claisen rearrangement of the bisprenyl ether (2) of 4,6-diacetylresorcinol (1) has been studied by refluxing in different solvents like N,N-dimethylaniline, o-xylene and n-decane and also by heating it neat in a sealed tube at 155 deg C and 185 deg C. 5,7-Diacetyl-2,3-dihydro-4-hydroxy-2,3,3-trimethylbenzofuran (3) is found to be the major product along with 3-acetyl-2,4-dihydroxy-5-(3,3-dimethylallyl)acetophenone (4) and 5-acetyl-2,4-dihydroxy-3-(3,3-dimethylallyl)acetophenone (5).The products have been characterised by their spectral data (IR, UV, PMS and mass) and their formation has been rationalised.
