Obliquetol 5 has been synthesised for the first time using improved conditions for prenyloxy-coumarin Claisen rearrangements. Efficient syntheses of obliquetin 6 and the related dihydrofuranocoumarin, nieshoutin 13 are also reported. The structure assigned to the natural coumarin, celerin, requires revision.
