Regioconvergent Nucleophilic Substitutions with Morita–Baylis–Hillman Fluorides

Abstract

Lithium iodide enables regioconvergent C−F bond functionalization of isomeric Morita−Baylis−Hillman fluorides with carbon, sulfur, and nitrogen nucleophiles. The defluorinative carbon−carbon and carbon− heteroatom bond formations give multifunctional compounds in excellent yields and with good to high diastereoselectivities at room temperature. The possibility of catalytic enantioselective allylation is also discussed.
