  In the aim of developing new procedures for efficient oligosaccharide assembly, a range of S-thiazolinyl (STaz) glycosides have been synthesized. These novel derivatives were evaluated against a variety of reaction conditions and were shown to be capable of being chemoselectively activated in the armed-disarmed fashion. Moreover, the S-thiazolinyl moiety exhibited a remarkable propensity for selective

  为了开发有效寡糖组装的新方法，已合成了一系列S-噻唑啉基（STaz）糖苷。这些新颖的衍生物针对各种反应条件进行了评估，并显示出能够以武装-解除武装的方式进行化学选择性活化。此外，与其他常见的离去基团相比，S-噻唑啉基部分显示出显着的选择性活化倾向。相反，可以在STaz部分上选择性激活各种离去基团，从而允许STaz / S-乙基和STaz / S-苯基正交方法。为了证明新型STaz衍生物的多功能性，已经以收敛的选择性，正交和化学选择性方式合成了许多寡糖靶标。

  Stepwise glycosidation was adopted for the construction of glycyrrhetic acid β-glycosides (27-30) having β(1→2)-linked disaccharides such as 2-O-β-D-flucuronopyranosyl-β-D-glucopyranose, 2-O-β-D-glucuronopyranosyl-β-D-galactopyranose, 2-O-β-D-glucopyranosyl-β-D-glucuronopyranose and 2-O-β-D-galactopyranosyl-β-D-glucuronopyranose. In the first glycosidation, 2-O-trichloroacety-β-D-pyranosyl chlorides (9-11) were utilized as starting sugar derivatives to react with methyl glycyrrhetinate (5) : Glycosidation of 5 with 9 and 10 gave β- and α-monoglycosides (12) and (13), and (15) and (16), respectively. Treatment of the β-glycoside 12 and 15 with ammonia-saturated ether gave products (14) and (17), respectively. The glycosidation of 5 with 11 followed by treatment with ammonia-saturated ether gave compounds (18) and (19), respectively. The second step glycosidations of 14 and 17 with methyl 2, 3, 4-tri-ο-acetyl-α-D-glucuronatopyranosyl bromide (20) gave diglycoside derivatives (23) and (24), respectively, and that of 18 with 2, 3, 4, 6-tetra-O-acetyl-α-D-glucopyranosyl bromide (21) and -α-D-galactopyranosyl bromide (22) gave deglycoside derivatives (25) and (26), respectively. The removal of the protecting groups of 23-26 gave diglycosides 27-30, respectively, having a β-D-glucuronopyranose (β-D-glcUA) as one of two sugar components in the molecules. The cytoprotective effects of the synthesized glycosides 27-30 on carbon tetrachloride (CCl4)-induced hepatotoxicity in vivo were compared with deglycosides 31-33 having only neutral sugar components, and naturally occurring glycyrrhizin (34) having two acidic sugar components (β-D-glcUA). While glycosides 31-33 had no cytoprotective effect, glycosides 27-30 showed potent effects. Especially, 27 and 28, having a β-D-glcUA as the terminal sugar component, were more effective meterials against hepatic injury than glycyrrhizin 34.

  采用分步糖苷化法构建了具有β(1→2)连接的二糖的甘草酸β-糖苷（27-30），这些二糖包括2-O-β-D-氟尿喹喃糖基-β-D-葡萄糖、2-O-β-D-古糖喹喃糖基-β-D-半乳糖、2-O-β-D-葡萄糖喹喃糖基-β-D-古糖和2-O-β-D-半乳糖喹喃糖基-β-D-古糖。在第一次糖苷化中，使用了2-O-三氯乙酰-β-D-吡喃糖氯化物（9-11）作为起始糖衍生物，与甘草酸甲酯（5）反应：5与9和10的糖苷化分别得到了β-和α-单糖苷（12）和（13），以及（15）和（16）。 β-糖苷12和15与氨饱和醚反应后分别得到产物（14）和（17）。5与11的糖苷化，再与氨饱和醚反应，分别得到了化合物（18）和（19）。14和17与甲基2, 3, 4-三-O-乙酰-α-D-古糖喹喃糖溴化物（20）的第二步糖苷化分别得到二糖苷衍生物（23）和（24），而18与2, 3, 4, 6-四-O-乙酰-α-D-葡萄糖喹喃糖溴化物（21）和-α-D-半乳糖喹喃糖溴化物（22）的糖苷化分别得到去糖苷衍生物（25）和（26）。去除23-26的保护基团分别得到二糖苷27-30，这些化合物在分子中有一个β-D-古糖喹喃糖（β-D-glcUA）作为两个糖组分之一。合成的糖苷27-30对四氯化碳（CCl4）诱导的肝毒性在体内的细胞保护作用与去糖苷31-33（只有中性糖组分）及天然存在的甘草苷（34，具有两个酸性糖组分 β-D-glcUA）进行了比较。虽然糖苷31-33没有细胞保护作用，但糖苷27-30显示出显著的作用。尤其是，27和28作为末端糖组分具有β-D-glcUA，比甘草苷34对肝损伤的保护效果更佳。
