from the kineticresolution of (R, S)- α- furfuryl amide using the modified Sharpless asymmetric epoxidation, have been transformed into four δ-hydroxy α-amino lactones (1S, 3S)-1, (1R, 3R)-1, (1S, 3R)-1, (1R, 3S)-1, usingSharpless asymmetric dihydroxylation as the key step. The much more efficient method of the addition of chiral aldimine 10 with allylic Grignard reagent for preparation of (S, S)-1
