Optically pure enantiomers of the chiral tetrahydroxythiepane derivative 3,6-dihydroxy-4,5-O-isopropylidene-thiepane (3) are obtained using a novel protocol in which a library of all possible stereoisomers of 3 is synthesized, followed by two-step stereoselective chromatography, using, first, conventional achiral and, then, chiral
