of 2,4- and 2,5-cyclohexadiene-1,3-dicarboxylates were functionalized at the allylic position via oxidation (SeO2, PDC/t-BuOOH) and halogenation (NBS). The regiochemical outcome for different substrates and reactions was studied and the importance of factors such as reaction mechanism, steric hindrance and reaction intermediates stability was discussed. §Present address: GlaxoWellcomc Medicines Research
