A method is described for carrying out indium-mediated allylation reactions of phenacyl bromides in aqueous solution that form homoallylic bromohydrins. By employing subsequent base treatment, the homoallylic bromohydrins were converted to allylic epoxides. Finally, the process has been used as a key step in a concise sequence for the synthesis of 3-allylbenzofuran.
描述了一种用于在水溶液中进行铟介导的苯甲酰溴的铟介导的烯丙基化反应的方法,该方法形成均烯丙基溴代醇。通过采用随后的碱处理,将均烯丙基溴代醇转化为烯丙基环氧化物。最后,该方法已被用作简明序列中3-烯丙基苯并呋喃合成的关键步骤。
