Abstract
The total synthesis of a demethoxy-egonol isolated fromStyrax obassia, 5-(3-hydroxypropyl)-2-(3′,4′-methylenedioxyphenyl)benzofuran (9), is described. The key steps involve the construction of a 2-arylbenzofuran skeleton7 from methyl 3-(4-hydroxyphenyl)propionate with 2-chloro-2-methylthio-(3′,4′-methylenedioxy)acetophenone (6) in the presence of ZnCl2 and successive desulfurization of the resulting product7.
