Ru-catalyzed cycloisomerization of a 1,3-diene and the alkene of an N-dienyl-2-vinylaniline substrate proceeded smoothly, leading to a 3-exomethylene-2-vinylindole derivative in good yield. This useful synthon was successfully applied to the total synthesis of (±)-cinchonaminone.
Ru催化的1,3-二烯和N-二烯基-2-乙烯基苯胺底物的烯烃的环异构化顺利进行,以良好的产率得到3-外亚甲基-2-乙烯基吲哚衍生物。这种有用的合成子成功地应用于 (±)-辛可胺酮的全合成。
