Treatment of guaiazulene (1) with NBS in hexane gave exclusively 3-bromo compound, while in benzene it afforded various side-chain-brominated compounds.Shifts of bromine atom catalyzed by succinimide were observed in benzene, presumably via intermolecular radical pathways.Using these reactions, various side-chain-functionalyzed derivatives of 1, including epoxy compounds, were prepared.
