Regio- and stereoselective iodinations under controlled Garegg conditions were performed on vicinaldiols and contiguous triols located on pyranose templates. P- D -Fructo- or psicopyranose-based diols were selectively iodinated at C-5 or C-4, respectively, to afford the L -sorbo or D -tagato iodohydrins. In contrast, the related triols only underwent selective iodination at C-5. Application of the
