An enantiospecificsynthesis of the tetrahydrofuran amino acid (2S,5S)-5-(aminomethyl)-tetrahydrofuran-2-carboxylic acid 1 is reported. The sugar enone 2-(S)-octyl 6-O-acetyl-3,4-dideoxy-α-d-glycero-hex-3-enopyranosid-2-ulose 2a, derived from galactose, was employed as a chiral precursor. The enone 2a was converted by chemical manipulation of the functional groups into the 6-azido-2-O-tosyl-3,4,6-
