  Synthesis of 8-Aryl-Substituted Coumarins Based on Ring-Closing Metathesis and Suzuki–Miyaura Coupling: Synthesis of a Furyl Coumarin Natural Product from Galipea panamensis

  摘要：

  The synthesis of 7-methoxy-8-(4-methyl-3-furyl)-2H-chromen-2-one, a natural product with antileishmanial activity recently isolated from the plant Galipea panamensis, is described. The key step is a Suzuki-Miyaura coupling of a furan-3-boronic acid and an 8-halocoumarin, which is advantageously synthesized using a ring-closing metathesis reaction. Several non-natural analogues are also available along these lines.
