  Synthesis of differentially protected ribitol derivatives from 3,4-O-benzylidene-d-ribono-1,5-lactone

  摘要：

  Several differentially protected ribitol derivatives were synthesised using 3,4-O-benzylidene-D-ribono-1,5-lactone as versatile starting compounds for oligosaccharide synthesis. The obtained ribitol derivatives allow the regiospecific coupling of glycosyl donors to either of the hydroxyl groups of ribitol and can be applied for the preparation of polyhydroxylated compounds.

  A series of 3-C-alkyl- (and 3-C-phenyl-) 2,3-dideoxy-D-erythro-pentono-1,4-lactones, compounds which are important in the synthesis of modified nucleosides and antibiotic sugars, were synthesized from D-ribonolactone. By a route that proceeded via 5-O-protected D-ribonolactone, 5-O-protected 2,3-dideoxy-D-glycero-pent-2-enono-1,4-lactones were synthesized and reacted with R2CuLi or a complex PhSCu(RMgBr)n

  一系列3-C-烷基-（和3-C-苯基-）2，3-二脱氧-D-赤-戊基-1，4-内酯，这些化合物在合成修饰的核苷和抗生素糖中很重要，由D-核糖内酯合成。通过经由5-O-保护的D-核糖内酯进行的途径，合成了5-O-保护的2,3-二脱氧-D-甘油-戊-2-enono-1,4-内酯，并与R2CuLi或络合物反应用PhSCu（RMgBr）n分别得到3-C-烷基或3-C-苯基化合物。提供了O-保护的中间体的制备以及有机金属试剂的选择的细节。
