(1-methylcyclohept-4-enyl) methyl brosylate 1b and 2-(1-methylcyclohex-3-enyl) ethyl brosylate 2b leads, as in the case of (cyclohept-4-enyl) methyl brosylate 1a and 2-(cyclohex-3-enyl) ethyl brosylate 2a, to bicyclic products. The brosylate 2b is 23 times more reactive, at 80°, than the brosylate 2a, whereas the brosylate 1b is 50 times less reactive than the brosylate 1a. The low reactivity of 1b is
