enantiomeric purity from readily available anti-N-Boc-1-tert-butyldimethylsilyl-3-amino-1,2-diols. The preparation of the anti series is straightforward, and takes place by protection of the secondary hydroxyl group (1-ethoxyethyl) followed by desilylation/oxidation of the primary hydroxyl group. For the preparation of the syn isomers, the secondary alcohol is inverted at the beginning of the sequence by Mitsunobu
