An optimized method for the synthesis of an important chiral scaffold, (3S,4R,5R)-1-N-Boc-3,4-isopropylidene-3,4,5-trihydroxypiperidine, was developed. Using this intermediate, the preparation of various chiral aminodihydroxypiperidines and their transformation into a series of non-glycosidic, six-membered azanucleosides was accomplished.
