Asymmetric synthesis of the Abbott amino dihydroxyethylene dipeptide isostere subunit

The aminodiol 1b, a N-benzyl protected form of the Abbott dipeptide isostere 1a is prepared, starting from an appropriate α,β-unsaturated ester, involving an asymmetric dihydroxylation and a rearrangement of an intermediate anti α,β-aminoepoxide.

A Versatile, Efficient Synthesis of (-)-(2S, 3R, 4S)-2-Amino-1-cyclohexyl-3,4-dihydroxy-6-methylheptane, The Abbott Pseudodipeptidyl Insert

An economic construction (6 steps, 36percent yield) of a valuable peptide analog subunit, the Abbott pseudodipeptidyl insert (-)-(2S,3R,4S)-2-amino-1-cyclohexyl-3,4-dihydroxy-6-methylheptane (1), has been developed.
