This study presents three efficient methods for five‐membered ring carbocycle synthesis using samarium(II) reagents. Simple organic starting materials engage in intramolecular Reformatsky aldol, enolate alkylation, and pinacol cyclizations. A promising lead result has also been established demonstrating enantioselectivity in a chiral ligand controlled Reformatsky aldol reaction.
