AbstractAn unexpected addition of acetic acid to ortho‐electron‐deficient alkynyl‐substituted aryl aldehydes catalyzed by palladium(II) acetate was achieved, which provided a convenient method for the synthesis of dihydroisobenzofurans in moderate to good yields. The electron‐withdrawing groups attached to alkynes may play an important role for the cyclization.magnified image
