Abstract
The preparation of some chiral spiroketals from carbohydrate precursors is described. The reversibility of the Lewis acid-catalysed ketalisation reaction ensured the dominance of the anomeric effect in determining the stereochemical outcome of the spiroketalisation step. In this way, enantiomerically pure products could be obtained from readily available starting materials.
