  Synthesis of 3-amino-2,3,6-trideoxy-2-fluoro-l-talose and -d-allose [(R)-2-fluoro-l-daunosamine and (R)-2-fluoro-d-ristosamine]

  摘要：

  The title compounds were synthesized (as methyl glycosides) starting from 1,3,4,6-tetra-O-acetyl-2-deoxy-2-fluoro-beta-D-glucopyranose. Stereoselective methods of glycosylation gave, via the tri-O-acetylglycopyranosyl bromide, the methyl 2-deoxy-2-fluoro-alpha- and -beta-D-glucopyranoside triacetates. Each anomer was O-deacetylated and further transformed into the corresponding, 4,6-O-benzylidenated 3-triflate, and the triflates were converted by azide displacement into the 3-azido-2,3-dideoxy-2-fluoroglycosides having the D-allo configuration. Hanesssian-Hullar reaction then furnished the corresponding 6-bromo-6-deoxy-4-benzoates, which were dehydrobrominated to give the methyl 3-azido-4-O-benzoyl-2,3,6-tri-deoxy-2-fluoro-alpha- and -beta-D-ribo-hex-5-enopyranosides. Debenzoylation of the alpha-anomer, followed by catalytic hydrogenation, led to methyl 3-amino-2,3,6-trideoxy-2-fluoro-beta-L-talopyranoside [methyl (R)-2-fluoro-beta-L-daunosaminide], whereas the same sequence applied to the beta-anomer afforded methyl 3-amino-2,3,6-trideoxy-2-fluoro-beta-D-allopyranoside [methyl (R)-2-fluoro-beta-D-ristosaminide]. The overall yields for these 10-step sequences were 11-12 and 16%, respectively. The 1H- and 13C-n.m.r. data for the new fluoro sugar derivatives are discussed with respect to the dependence of JF,H and JF,C values on molecular geometry and substituent effects.

  silver perchlorate-catalyzed glycosylation showed remarkable lack of stereoselectivity for the formation of the corresponding methyl alpha-glycoside, despite the presence at C-2 of the fluorine functionality presumably not capable of neighboring-group participation. Pure methyl 2-deoxy-2-fluoro-alpha- and beta-D-glucopyranosides were obtained by fractional crystallization from the mixture formed by methanolysis

  Methyl 3-O-benzyl-4, 6-O-benzylidene-2-O-(trifluoromethanesulfonyl)-β-D-mannopyranoside (7) was examined as a substrate for the preparation of 2-deoxy-2-fluoro-D-glucose (1) by fluoride ion treatment. The triflate (7) reacted rapidly with tetraalkylammonium fluorides in acetonitrile or tetrahydrofuran to give methyl 3-O-benzyl-4, 6-O-benzylidene-2-deoxy-2-fluoro-β-D-glucopyranoside (10) in 52-57% yield. Removal of the protecting groups from 10 by the use of 50% methanesulfonic acid afforded the required 1 in good yield. This synthetic sequence may provide an effective alternative to known methods for preparing 18F-labeled 1.

  研究人员将 3-O-苄基-4，6-O-亚苄基-2-O-(三氟甲磺酰基)-β-D-吡喃甘露糖苷（7）作为底物，通过氟离子处理制备 2-脱氧-2-氟-D-葡萄糖（1）。三酸酯（7）与四烷基氟化铵在乙腈或四氢呋喃中迅速反应，得到甲基 3-O-苄基-4，6-O-亚苄基-2-脱氧-2-氟-β-D-吡喃葡萄糖苷（10），收率为 52-57%。用 50%的甲磺酸去除 10 中的保护基团，可以得到所需的 1，收率很高。这种合成方法可以有效替代已知的 18F 标记 1 的制备方法。
