Bowdenol, a New 2,3-Dihydrobenzofuran Constituent from Bowdichia Virgilioides

Abstract

Abstract From the stem bark of Bowdichia virgilioides, lupeol, lupeol acetate, sitosterol, stigmasterol and methyl-3-[2-(1-hydroxymethylvinyl)2,3-dihydrobenzo[b]furan-5-yl]-(E)-2-propenoate have been isolated. The latter is a new compound and it has been named as bowdenol. Their structures were elucidated with the aid of spectroscopic techniques, mostly 1 and 2D NMR. The biogenetic pathway for bowdenol has been suggested.
