I7O NMR chemical shifts of 2-oxo-1,3,2-dioxathiane and 13 of its methyl-substituted derivatives are reported. The chemical shifts depend strongly on temperature and to a much smaller extent on concentration. As a whole, however, they strongly support the predominance of chair conformations in these
