Chemistry Department, Faculty of Science, M. S. University of Baroda, Baroda-390 002 Manuscript received 22 August 1979, accepted 4 March 1980 2-Hydroxy5-allyloxyacetophenone(Ia), on Claisen condensation with ethyl formate in the presence of sodium yielded 2-hydroxy-2,3-dibydro-6-allyloxychromone (IIa), which on dehydration and Claisen rearrangement gave 5-allyl-6-hydroxycbromone (IVb). Cyclization of (IVb) with cone. sulphuric acid afforded 2-methyl-2,3-dihydro-4H-furo (3,2-f) benzopyran-4-one (Va). This on dehydrogenation with palladised charcoal furnished 2-methyl-4H-furo(3, 2-f) benzopyran-4-one(VIa). 4H-Furo (3, 2-f) benzopyran-4-one(VIb) was synthesised from (IVb) by carrying out oxidation with osmium tetroxide and potassium perio...
