Abstract: | The synthesis is described of 3-amino-2,3-dideoxy-l-arabino-hexose (10), methyl 2,3-dideoxy-3-trifluoroacetamido-α-l-lyxo-hexopyranoside (17), methyl 3-amino-2,3-dideoxy-α-l-ribo-hexopyranoside (21), methyl 2,3-dideoxy-3-trifluoroacetamido-α-l-xylo-hexopyranoside (26), and certain derivatives from methyl 4,6-O-benzylidene-2-deoxy-α-l-arabino-hexopyranoside (3). Conversion of 2-deoxy-l-arabino-hexose into 3 by modified, standard procedures, and on a large scale, gave a 75% yield. |
