Rh^I‐Catalyzed Two‐Component [(5+2)+1] Cycloaddition Approach toward [5‐8‐5] Ring Systems

Abstract

Bringing it all together: [{Rh(CO)2Cl}2]-catalyzed two-component [(5+2)+1] cycloaddition of ene-vinylcyclopropanes with various tether types and substituents with CO has been designed for the one-pot synthesis of fused tricyclic cyclooctenones with atom and step economies.
