| dc.description.abstract | 3-[Cyclopent-2-enyl]-4-hydroxy[1]benzopyran-2-one 3 has been prepared by the reaction of 3-chlorocyclopent-2-ene 2 and 4-hydroxy[1]benzopyran-2-one 1. Compound 3 or its acetate 4 on treatment with pyridine hydrotribromide in dichloromethane at 0-5°C for 2 hr gives fused furo chromone 5 in 90 % yield. Compound 5 on refluxing in 50 % sulphuric acid rearranges to the fused furocoumarin 7 in 87 % yield. | en_US |
