Strain-Induced Regioselective Ring-Opening Cross-Metathesis of Hybrid Cage Propellane Containing both Bicyclo[2.2.1]heptene and Bicyclo[2.2.2]octene Units

Abstract

AbstractHerein, we report strain-driven regioselective tandem ring-opening cross-metathesis (ROCM) of a linearly fused cage system that contains both bicyclo[2.2.1]heptene and bicyclo[2.2.2]octene units fused to the same cage system. The synthesis of novel cage propellane involves Diels–Alder cycloaddition and [2+2] photocycloaddition as key steps.
