Abstract

The non-natural enantiomer of polyoxamic acid (1) and 3, 4-diepipolyoxamic acid (2) was synthesized in four steps from d-lyxono-1, 4-lactone (4). Regioselective bromination of unprotected d-lyxono-1, 4-lactone with HBr/AcOH led to 2-bromo-2-deoxy-d-xylono-1, 4- lactone (5). This intermediate was treated with NaN3 to give 2-azido-2-deoxy-d-lyxono and xylono-1, 4-lactones. Saponification of the obtained 2-azido derivatives gave the ...
