  Efficient and stereoselective 1,2-cis glycoside formation of 5-thioaldopyranoses: glycosylation with peracetylated 5-thio-D- arabinopyranosyl and 5-thio-L-fucopyranosyl trichloroacetimidates

  摘要：

  Trichloroacetimidate method was proved to be effective for 5-thio-D-arabinopyranosylation and 5-thio-L-fucopyranosylation of N-acetyl-D-glucosaminides and D-galactosides. In these 5-thioglycosylation the neighboring group participation of 2-0-acetyl function was not decisive of anomeric stereoselectivity to give 1,2-cis pseudodisaccharides predominantly. Allyl 2-O-(5-thio-alpha-L-fucopyranosyl)-beta-D-galactopyranoside showed potent inhibitory activity toward alpha-L-fucosidase (Ki = 30muM).

  摘要：

  摘要由5-O-三苯甲基-d-阿拉伯糖基呋喃糖或d-阿拉伯糖二乙基二硫缩醛在C-5上一键延伸，合成了11个步骤的5-巯基-呋喃葡萄糖四乙酸酯。实现了将醚中的MeLi高度非对映选择性地添加到1,2-O-异亚丙基-β-d-阿拉伯糖基戊二醛-1,4-呋喃糖衍生物中，得到相应的6-脱氧-β-d-呋喃糖异构体。良品率高。通过在HMPA中用KSAc取代5-甲苯磺酸酯并反转构型，将硫原子引入6-脱氧-d-呋喃呋喃糖衍生物的C-5处，得到5-硫-1-呋喃葡萄糖。还由6-脱氧-β-d-呋喃糖衍生物制备3-O-取代的-1-岩藻糖衍生物。5-硫代-1-呋喃糖的5-脱甲基类似物5-噻吩基-阿拉伯吡喃喃糖四乙酸酯也由5个步骤由5-O-三苯甲基-d-阿拉伯呋喃糖合成。

  5-S-Benzoyl-2,3-O-isopropylidene-5-thio-L-arabinose, prepared from L-arabinose diethyl dithioacetal gave, on treatment with sodium methoxide in methanol, 4-O-benzoyl-2,3-O-isopropylidene-5-thio-L-arabinopyranose 12 which was converted into its 1-O-acetate 14. Hydrolysis of 12 in acetic acid-water afforded, after acetylation, 1,2,3-tri-O-acetyl-4-O-benzoyl-5-thio-L-ara-binopyranose 17 which was transformed into 2,3-di-O-acetyl-4-O-benzoyl-5-thio-L-arabinopyranosyl bromide 20. Zemplen deacylation of 17 gave 5-thio-L-arabinopyranose which was converted via 1,2,3,4-tetra-O-acetyl-5-thio-beta-L-arabinopyranose 5 into 2,3,4-tri-O-acetyl-5-thio-beta-L-arabinopyranosyl bromide 6 and into O-(2,3,4-tri-O-acetyl-5-thio-L-arabinopyranosyl) trichloro-acetimidate 7. Glycosidation of 4-nitrophenol with 12 under the Mitsunobu conditions afforded 4-nitrophenyl 4-O-benzoyl-2,3-O-isopropylidene-5-thio-alpha- and beta-L-arabinopyranoside in a similar to 1:2 ratio. Condensation of the glycosyl donors 6, 7, 17, and 20 with 4-cyano- and 4-nitrobenzenethiol yielded, after deacylation, 4-cyano- and 4-nitrophenyl 1,5-dithio-alpha- and beta-L-arabinopyranosides 28 alpha, 28 beta, 29 alpha and 29 beta in different ratios and yields, depending on the reaction conditions applied. In a similar manner the corresponding D-isomers 30 alpha, 30 beta, 31 alpha and 31 beta were also prepared. All of these glycosides, except 28 alpha, showed a stronger oral antithrombotic effect in rats as compared to beciparcil, used as reference. (C) 1998 Elsevier Science Ltd. All rights reserved.
