Synthesis of microfolicoumarin, a constituent of Cedrelopsis microfoliata.
Microfolicoumarin (1), a prenylcoumarin from Cedrelopsis microfoliata, was synthesized from 2,4,5-trimethoxybenzaldehyde in five steps. 1 did not show significant antioxidative activity, but the key intermediates, esculetin (3) and 5-prenylesculetin (6), exhibited strong antioxidative activity in both the superoxide-radical and 1,1-diphenyl-2-picrylhydrazyl radical-scavenging models.
