paper. The synthesis of rotenone involves two key transformations, the first of which is a Pd π-allyl mediated cyclisation for the construction of the dihydrobenzofuran skeleton. The second is a 6-endo-hydroarylation which yields the chromene as a precursor to rotenone. The synthesis of rotenone was achieved in 17 steps from resorcinol and constitutes the first stereoselective synthesis of this complex
本文报道了鱼藤酮和芒硝的总合成。鱼藤酮的合成涉及两个关键的转变,第一个是Pdπ-烯丙基介导的环化反应,用于构建二氢苯并呋喃骨架。第二个是6-内-氢芳基化,其产生色烯作为鱼藤酮的前体。鱼藤酮的合成是由间苯二酚分17步完成的,构成了这种复杂天然产物的首次立体选择性合成。
