摘要:
The phytoalexin resveratrol has been made using a decarbonylative Heck reaction. The acid chloride derived from 3.5-dihydroxybenzoic acid was coupled with 4-acetoxystyrene in the presence of palladium acetate and N,N-bis-(2,6-diisopropylphenyl)dihvdroimidazolium chloride to give the substituted stilbene in 73%, yield as the key step.
