Stereoselective Synthesis of Tri‐ and Tetrasubstituted Alkenes by Iron‐Catalyzed Carbometalation Ring‐Opening Reactions of Cyclopropenes

Abstract

Open sesame: An iron-catalyzed cyclopropene carbometalation ring-opening sequence using trialkylaluminum reagents is described. The reactions proceed with high levels of regio- and stereocontrol to provide a range of multisubstituted alkenes, including trisubstituted vinylsilanes, trisubstituted vinylstannanes, and all-carbon tetrasubstituted alkenes.
