A four‐step synthesis of the extracyclic, antimalarial indole natural product decursivine is described starting from commercial piperonyl bromide and serotonin (see scheme). A photoinitiated reaction cascade involving indole radical cation formation, rearrangement, radical recombination, rearomatization, elimination, and diastereoselective auto‐acid‐catalyzed closure of the dihydrofuran ring combine
描述了从商业胡椒基溴化物和5-羟色胺开始的环外抗疟吲哚天然产物地西西藤的四步合成法(参见方案)。光引发的反应级联反应涉及吲哚自由基阳离子形成,重排,自由基重组,重新麦芽糖化,消除和非对映选择性自酸催化的二氢呋喃环的封闭,这些步骤在一个单一步骤中完成,从而得出了这一非常有效的合成方法。
