The stereochemistry of some new spiro-1,3-dioxanes exhibiting axial and helical chirality was investigated using NMR methods. The compounds display semiflexible or anancomeric structures in correlation with the number and type of substituents located on the rings. The influence of the chirality of the spiro skeleton was revealed by the diastereotopicity of protons and carbon atoms.
