The asymmetric synthesis of the nonproteinogenic aminoacids (2S,3S,4′S)-β-hydroxyenduracididine 3 and (2R,3S,4′S)-β-hydroxyenduracididine 4 in orthogonally protected form in 15 total steps from Garner’s aldehyde is reported. The former and N-glycosylated form of the latter are found in the glycopeptide antibiotic mannopeptimycin.
