Radical addition of PhSO2Hlg (Hlg = Cl, Br) to 1-phenylthiotricyclo[4.1.0.02,7]heptane results in endo,syn-stereoselective splitting of the central bicyclobutane C1-C7 bond with formation of norpinane derivatives. The latter readily undergo substitution of the halogen by the action of nucleophiles (H2O, MeONa, PhSNa) and 1,3-dehydrohalogenation to 1-phenylsulfonyl-7-phenylthiotricyclo[4.1.0.02,7]heptane by the action of t-BuOK in THF. The stereoselective endo,syn addition of benzenesulfenyl chloride and benzeneselenol and also addition of benzenethiol in the presence of H2SO4 at the C1-C7 bond follows the Markownikoff rule. Acid-catalyzed hydration and bromohydroxylation with N-bromosuccinimide result in formation of 6-norpinanone derivatives.
