摘要

The biomimetic synthesis of the bisesquiterpene lactones (±)-biatractylolide 1 and (±)- biepiasterolide 2 via dimerization of the captodative stabilized radical 8 is reported. Atractylon 7 has also been shown to be a possible intermediate during the biosynthesis of biatractylolide 1, biepiasterolide 2, atractylolide 3, and hydroxyatractylolide 4.
