The RhI-catalyzed intramolecular [5+2–2]-type cycloisomerization of allene–allenylcyclopropanes was developed. In this reaction, ethylene was liberated from the cyclopropane ring to afford the 1,5,6,7-tetrahydroazulene skeletons.
开发了 RhI 催化的丙二烯-丙二烯基环丙烷的分子内 [5+2-2] 型环异构化。在该反应中,乙烯从环丙烷环中释放出来,得到 1,5,6,7-四氢薁骨架。
