  • Published:
Chemistry of Heterocyclic Compounds Aims and scope

Bromination of 1-allyl-substituted 3-(arylaminomethylene)quinoline-2,4-(1H,3H)-diones with one equivalent of molecular bromine in glacial acetic acid and subsequent dilution of the reaction mixture with water is accompanied by halocyclization and hydrolysis to form 2-bromomethyl-5-oxo-1,2 dihydro-5H-oxazolo[3,2-a]quinoline-4-carbaldehyde.
