Abstract: A direct conversion of 3-acetoxybenzofurans to 3-methoxybenzofurans was realized by refluxing in anhydrous methanolic solution containing hydrogen chloride.
The structure of gnetifolin A, previously proposed as (1), was revised to (2) on the basis of the original spectra of gnetifolin A and the spectral data of its synthetic analogs.
