A series of benzofuran derivatives have been synthesized by use of a microwave-assisted process. Substituted or unsubstituted ο -hydroxyacetophenone and salicylaldehyde reacted with ethyl bromoacetate, ω-bromoacetophenone, or chloroacetone under the action of potassium carbonate in DMF to yield substituted benzofuran derivatives. Compared with conventional heating, this microwave-assisted synthetic
通过使用微波辅助方法已经合成了一系列苯并呋喃衍生物。在DMF中碳酸钾的作用下,取代或未取代的 邻 羟基苯乙酮和水杨醛与溴乙酸乙酯,ω-溴苯乙酮或氯丙酮反应,生成取代的苯并呋喃衍生物。与常规加热相比,该微波辅助合成工艺具有操作更方便,反应时间更短,产率更高的优点。
