Synthesis of Highly Functionalized Cyclohexenone Rings: Rhodium‐Catalyzed 1,3‐Acyloxy Migration and Subsequent [5+1] Cycloaddition

Abstract

Lead Rh-ole: Highly substituted cyclohexenones were prepared from cyclopropyl-substituted propargyl esters by using a [{Rh(CO)2Cl}2] catalyst. This metal catalyst promoted the 1,3-acyloxy migration of propargyl esters and a subsequent [5+1] cycloaddition of the resulting allenylcyclopropanes in the presence of CO with high regioselectivity.
