Xg. She et al., A convenient synthesis of (+/-)-3-methoxybenzodioxane-4,9,9 '-triol neolignan, and methyl ethers of isoamericanol A and isoamericanin A, J CHEM R-S, (2), 1999, pp. 100-101
The (+/-)-3-methoxybenzodioxane-4,9,9'-triol neolignan 9, and methyl ethers
of isoamericanol A 8 and isoamericanin A 7 were synthesized from the readi
ly available materials caffeic acid and ferulic acid, using a coupling reac
tion as a key step.
