  Synthesis of 4-cyanophenyl and 4-nitrophenyl 1,5-dithio-d-ribopyranosides as well as their 2-deoxy and 2,3-dideoxy derivatives possessing antithrombotic activity

  摘要：

  1,2,3,4-Tetra-O-acetyl-5-thio-D-ribopyranose as well as its 1-bromide were used as donors in the reaction with 4-cyano- and 4-nitrobenzenethiol to give the corresponding thiogrycosides in different anomeric ratios depending on the reaction conditions. Zemplen deacetylation afforded 4-cyanophenyl as well as 4-nitrophenyl 1,5-dithio-alpha- and beta-D-ribopyranosides, respectively. 1,3,4-Tri-O-acetyl-2-deoxy-5-thio-D-erythro-pentopyranose was synthesized from methyl 2-deoxy-D-erythro-pentofuranoside and was coupled with 4-cyano- and 4-nitrobenzenethiol to give anomeric mixtures from which 4-cyanophenyl as well. as 4-nitrophenyl. 1,5-dithio-beta-D-erythro-pentopyranosides were isolated after deacetylation. 1,4-Di-O-acetyl-2,3-dideoxy-5-thio-D-glycero-pentopyranose was obtained starting from 1,2;5,6-di-O-isopropylidene-D-mannitol and used as the donor in the glycosylation reaction with 4-cyano- and 4-nitrobenzenethiol. The resulting anomeric mixtures were separated to give, after deacetylation, 4-cyanophenyl as well as 4-nitrophenyl 2,3-dideoxy-1,5-dithio-beta-D-glycero-pentopyranosides. All of these thioglycosides showed significant antithrombotic activity on rats after oral administration. (C) 1999 Elsevier Science Ltd. All rights reserved.

  Glycosyl thiocyanates having hydroxyl groups protected with acetyl or benzoyl groups react readily at −40°C with Grignard reagents to afford the corresponding alkyl or aryl thioglycosides in good yields. Monosaccharide derivatives having the SCN grouping at other positions form under similar conditions thioethers. Axial thiocyanates do not react. Elevated temperatures induce side reactions leading

  在-40℃下，具有被乙酰基或苯甲酰基保护的羟基的糖基硫氰酸氰酸酯易于与格氏试剂反应，以高收率得到相应的烷基或芳基硫代糖苷。在相似条件下形成在其他位置具有SCN基团的单糖衍生物可形成硫醚。轴向硫氰酸盐不反应。升高的温度引起副反应，导致硫醇。
