Conformational studies (1,2) of the cyclic sulfites of 2-substituted-propane-1,3-dials have indicated that these esters occupy preferentially a chair form with axial S=O bond. X-ray analyses (3,4) of two compounds have shown that the sulfite group holds the remainder of the ring in au almost ideal s
