compounds both the open-chain 2-bromoalkyl derivatives and their cyclic isomers. Substitutionreactions of bromoalkyl compounds may be assisted by polar solvents and by neighbouring group effect of hydrazinocarbonyl moiety. Nucleophiles attack the condensed oxazolinium ring in tricyclic intermediates at the saturatedcarbon bonded to the oxygen with ring opening. Addition of piperidine to unsaturated
