A strategy for the asymmetric aminohomologation of α,β-dihydroxy aldehydes: Application to the synthesis of the southwest tripeptide segment of echinocandin B

The synthesis of the (2S,3S,4S)-3,4-dihydroxyhomotyrosine amino acid segment, present in echinocandin B, in its activated form ready for peptide coupling is described. The key steps of the approach are the enantioselective AD reaction of 4-methoxycinnamic
