Rezumat:

The stereochemistry of some new chiral brominated 1,3-dioxane derivatives is investigated by NMR methods. The anancomeric structure of the compounds and the diastereotopicity of the homomorphic groups are revealed. An influence through space of the chiral center at a distance of eight bonds have been observed.
