A general protocol for the simple, efficient, and mild synthesis of α,β-unsaturated
γ-amino sulfonyl fluorides is developed via a base-catalyzed N-alkylation reaction of aromatic amines with (E)-3-bromoprop-1-ene-1-sulfonyl fluoride. This transformation exhibits excellent chemo-
and stereoselectivity, mild conditions, broad functional group compatibility and operational
simplicity, making it a potentially valuable procedure in medicinal chemistry, chemical
biology, and drug discovery.
Key words
