Synthesis of 1-deoxy-4-thio-L-ribose starting from D-arabitol
摘要:
The synthesis of 1-deoxy-4-thio-L-ribose starting from D-arabitol is described. The keystep is the episulfonium rearrangenment of a protected 3,4,5-trihydroxy-tetrahydrothiopyran. Copyright (C) 1996 Elsevier Science Ltd

Versatile synthesis of some analogues of the naturally-occurring α-glucosidase inhibitor salacinol (1), involving thioanhydro alditol moieties with erythro, d,l-threo, xylo, ribo, d-arabino and d-manno configurations is described. Nucleophilic attack at the least-hindered carbon atom of an l- or d-protected erythritol cyclic sulfate by the thioanhydro alditol sulfur atom yielded the desired zwitterionic
多功能天然存在的α葡萄糖苷酶抑制剂的Salacinol(的一些类似物的合成1),涉及thioanhydro糖醇部分具有赤式,d,1-苏式,木糖,核糖,D-阿糖和D-甘露配置进行说明。硫代脱水醛糖醇硫原子对1-或d-保护的赤藓糖醇环状硫酸盐的最少受阻碳原子的亲核攻击产生了所需的两性离子化合物。此外,2,4-的环硫酸酯的制备ø -亚苄基- d赤藓糖醇和2,4- ö-异亚丙基-1-赤藓糖醇得到改善。酶抑制试验表明,大多数新化合物是弱的但特异性抑制剂,而六元环类似物(β-葡萄糖苷酶:K i = 16μM)则具有良好的抑制活性。
