Abstract
Toddamarin A, a new prenylated coumarin dimer with a new type of 1,3,4,4,5-pentasubstituted cyclohexene ring was isolated from the roots of Toddalia asiatica. Notably, it possessed both chiral centers and stereogenic axes, exhibiting atropisomeric property as evidenced by ROESY and variable temperature NMR experiment. Additionally, a plausible biosynthetic pathway was proposed. The finding enriched the chemical diversity of coumarins, and provided promising molecular template for stereoselective synthesis.
