N-Benzylimines derived from conveniently protected (R)-glyceraldehyde underwent diastereoselective phenylmagnesium bromide addition to afford the corresponding aminodiols, whose absolute configuration at the newly formed stereogenic carbon depends on the

A remarkable Lewis acid tuning has been observed in the nucleophilic addition of Grignard reagent to BIGN, the N-benzyl nitrone derived from 1,2- O-isopropylidene-D-glyceraldehyde. The obtained α,β-dialkoxy hydroxylamines can serve as starting points for the synthesis of both aminodiols and α- hydroxy-β-amino acids. This synthetic approach is illustrated by the synthesis of the antipode of the C-13 side chain of Taxotere as well as its C-3 epimer.
Stereocontrolled addition of Grignard reagents to α-alkoxy nitrones. Synthesis of syn and anti 3-amino-1,2-diols

The stereoselective addition of Grignard reagents to α-alkoxy nitrones has been achieved with excellent stereocontrol using ZnBr2 and Et2AlCl as precomplexing agents to obtain the corresponding syn- and anti- adducts, respectively. The obtained hydroxylamines have been transformed into valuable 3-amino-1,2-diols.
An enantioselective, stereodivergent approach to anti- and syn-α-hydroxy-β-amino acids from anti-3-amino-1,2-diols. Synthesis of the ready for coupling Taxotere side chain

Both anti- and syn-α-hydroxy-β-amino acids are efficiently synthesised in protected form and high 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
A convenient, stereodivergent approach to the enantioselective synthesis of N-Boc-aminoalkyl epoxides
Castejon, Patricia
, p. 3019 - 3022 (2007/10/02)
An efficient, stereodivergent and enantioselective synthesis of N-Boc-aminoalkyl epoxides has been developed. Starting from enantiomerically enriched anti N-diphenylmethyl-3-amino-1,2-diols, and after a change in the nitrogen protecting group, an intramol
