Iron-Catalyzed Cycloisomerization and C−C Bond Activation to Access Non-canonical Tricyclic Cyclobutanes

Research output: Contribution to journalResearch articleContributedpeer-review



Cycloisomerizations are powerful skeletal rearrangements that allow the construction of complex molecular architectures in an atom-economic way. We present here an unusual type of cyclopropyl enyne cycloisomerization that couples the process of a cycloisomerization with the activation of a C−C bond in cyclopropanes. A set of substituted non-canonical tricyclic cyclobutanes were synthesized under mild conditions using [(Ph3P)2Fe(CO)(NO)]BF4 as catalyst in good to excellent yields with high levels of stereocontrol.
