7-functionalised norbornenes. Thus the epoxide (13) of methyl 7-anti-trimethylsily bicyclo[2.2.1]hept-5-ene-2-endo-carboxylate (12) rearranges on treatment with boron trifluoride–ether to give methyl 7-anti-hydroxybicylo[2.2.1]hept-5-ene-2-exo-carboxylate (14), and treatment of (12) with bromine gives mainly the rearranged bromide, methyl 7-anti-bromobicyclo[2.2.1]hept-5-ene-2-exo-carboxylate (16)
