Abstract
The stereoselectivity of halomethoxylation of 1-phenyltricyclo[4.1.0.02,7]heptane and methyl 7-phenyltricyclo[4.1.0.02,7]heptane-1-carboxylate at the central bicyclobutane C1-C7 bond by the action of N-chloro-, N-bromo-, and N-iodosuccinimides in methanol depends on the halogen nature. Conjugate chlorination and bromination are characterized by pronounced anti-stereoselectivity; the contribution of syn-addition slightly increases in going from the monosubstituted tricycloheptane substrate to disubstituted. Iodomethoxylation of the latter is clearly syn-stereoselective.
