Conclusions
-
1.
The most probable conformation for bieyclo[4.1.0]heptane halohydrin derivatives and their methyl ether analogs in the carane series is a 1,2-diplanar form (anti-sofa) with a diequatorial arrangement of substituents.
-
2.
Vicinal halohydrins exist in a gauche-gauche conformation of the Hal-C-C-OR chain, with a 1,3-parallel bond orientation; in the case of methoxyhalo derivatives, this structure is present at equilibrium.
