Rezumat:

The stereochemistry of new spiro-1,3-oxathiane derivatives has been explored by NMR methods and the molecular structure of one compound established via single crystal by X-ray diffractometry. The investigations revealed flexible, semi-flexible and anancomeric structures and the ring-chain tautomerism of the 1,3-oxathiane heterocycle.
