A stereoselective chemoenzymatic synthesis of Fmoc-protected (2S,3S)-2-hydroxy-3-amino acids 6 is described. After the formation of cyanohydrin 2 from 2-furaldehyde in the presence of R-oxynitrilase and subsequent protection, 3 was transformed into fully protected ethanolamines 5. Ozonolysis provided the target compounds in good yields.
