  摘要：

  Treatment of 1-O-acetyl-3,4,6-tri-O-benzyl-2-deoxy-D-arabino-hexopyranose 18 with trimethyl phosphite in the presence of trimethylsilyl triflate gave a separable mixture of dimethyl (3,4,6-tri-O-benzyl-alpha-D-arabino-hexopyranosyl)phosphonate 19 (35%) and the beta-anomer 20 (60%). The diethyl analogue of compound 20 could be prepared stereoselectively from tributyl (3,4,6-tri-O-benzyl-2-deoxy-beta-D-arabino-hexopyranosyl)stannane 21 and diethyl chlorophosphate.Reaction of 1,3,4,6-tetra-O-acetyl-2-deoxy-D-arabino-hexopykanose 23 with trimethyl phosphite and trimethylsilyl triflate gave dimethyl (3,4,6-tri-O-acetyl-2-deoxy-alpha-D-arabino-hexopyranosyl)phosphonate 25 and the beta-anomer 27 with some alpha-selectivity. Deprotection of compounds 25 and 27 gave the phosphonic acids 11 and 12 respectively. The esters 25 and 27 could be converted into methyl 3,4,6-tri-O-acetyl-2-deoxy-1-(dimethoxyphosphoryl)-beta-D-arabino-hexopyranoside 31 by free-radical bromination followed by methanolysis, and diethyl [3,4,6-tri-O-(tert-butyldiphenylsilyl)-2-deoxy-D -arabino-hex-1-enopyranosyl)phosphonate 33 was prepared by interaction of the 1-lithioglucal with diethyl chlorophosphate.Metallation of stannane 21 and reaction with methyl chloroformate gave methyl 2,6-anhydro-4,5,7-tri-O-benzyl-3-deoxy-D-gluco-heptonate 35 which could be alkylated with tert-butyl bromoacetate to give, after deprotection, 3,7-anhydro-3-carboxy-2,4-dideoxy-D-gluco-octonic acid 14.
