Sets of coumarinyl ethers having chromone, benzofuranyl and 4-hydroxy coumarins (4, 5, 6) were prepared and tested for analgesic and antiinflammatory activity. The 4-(4'-acetyl-3'-hydroxy-phenoxymethyl)-coumarin 3 were synthesised by the reaction of 4-bromo methyl coumarin with 2, 4-dihydroxy acetophenones, were found to less active. Further compound 3 having the ortho hydroxy moiety was cyclised to chromones 4 and benzofurans 5 were found to enhance the analgesic and anti-inflammatory activity. The cyclisation to 4-hydroxy coumarin 6 was found to be reducing the anti-inflammatory and analgesic activity in this series. These newly synthesized compounds were found to produce less toxicity and less ulcerogenic effects.
