The dibromides 7–12 have been synthesized by addition of bromine to exocyclic α,β‐unsaturated ketones 1–6. The relative configurations and the stereochemistry of the products have been determined by NMR methods. Bromination of 3‐benzylideneflavanone (3) and its thio analogue 5 proved to be highly stereoselective.
