title: Synthesis of derivatives of 3-amino-2,3-dideoxy-L-hexoses related to daunosamine (3-amino-2,3,6-trideoxy-L-lyxo-hexose).
abstract: The synthesis is described of 3-amino-2,3-dideoxy-L-arabino-hexose (10), methyl 2,3-dideoxy-alpha-L-lyxo-hexopyranoside(17), methyl 3-amino-2,3-dideoxy-alpha-L-ribo-hexopyranoside (21), methyl 2,3-dideoxy-3-trifluoroacetamido-alpha-L-xylo-hexopyranoside (26), and certain derivatives from methyl 4,6-O-benzylidene-2-deoxy-alpha-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.
