| Abstract: | Purpurasol 1, a 6,7,8-trioxygenated coumarin, isolated from Pterocaulon purpurascens (Asteraceae) and Haplophyllum obtusifolium (Rutaceae), was synthesized for the first time by a three-step synthesis starting from the natural coumarin fraxetin. This synthesis confirmed unambiguously the structure of purpurasol 1 and obtusifol. |
