Highly functionalised benzofurans have been prepared from ortho‐hydroxyphenones and 1,1‐dichloroethylene. The key intermediate, a chloromethylene furan, smoothly rearranged into the corresponding benzofuran carbaldehyde under acidic conditions. Some mechanistic investigations have been performed and several biologically active benzofurans have been synthesised.
高度功能化的苯并呋喃是由邻羟基苯甲酮和1,1-二氯乙烯制备的。关键中间体氯亚甲基呋喃在酸性条件下平稳重排成相应的苯并呋喃甲醛。已经进行了一些机理研究,并且已经合成了几种具有生物活性的苯并呋喃。
