The highly stereoselective synthesis of (−)-epi-, (−)-allo- and neo-quercitols as well as stereospecific synthesis of (−)-talo- and (+)-gala-quercitols have been achieved. The general strategy is employing dihydroxylation of the isolated double bond of various kinds of protected chiral (1,4,5)-cyclohex-2-ene-triols, which are derived from d-(−)-quinic acid. The choosing of protecting groups from either
