✦ Synopsis

2-Deoxy-P-D-lyxo-hexose (2-deoxy+-D-galactose, C,H,,O,), M, = 164.16, is monoclinic, P2, with a = 9.811(l), b = 6.953(l), c = 5.315(l) A, p = 91.58(2)", V = 362.5(l) A3, Z = 2, and D, = 1.504 g.cme3. The structure was solved by direct methods (MULTAN 79) and refined to R = 0.032 for 800 observed reflections. Each hydroxyl oxygen, acting both as donor and acceptor, is involved in a hydrogen-bonding system, which consists of infinite helical chains around the crystallographic screw axes. Moreover, weak interactions allow the incorporation of the ring-oxygen atoms into an interconnected network.

Replacement of natural sugars by 4-deoxy-D-lyxo-hexose ("4-deoxy-D-mannose", 8) as the component parts of saccharides may endow compounds with new functions or biological activities. In previous studies, syntheses of 8 gave low overall yields or required many steps 1-4 Thus a simplified synthetic ro
