Abstract
The stereochemistry pf some new spiro-1,3-dioxanes exhibiting axial and hel ical chirality was investigated using NMR methods. The compounds display se miflexible or anancomeric structures in correlation with the number and typ e of substituents located on the rings. The influence of the chirality of t he spiro skeleton was revealed by the diastereotopicity of protons and carb on atoms.
