    摘要:
    将苯基 1-硫代-β-D-吡喃半乳糖苷(1)转化为两种亚砜糖基供体:苯基(2,3,4,6-四-O-苄基)-1-硫代-β-D-吡喃半乳糖苷 S-氧化物(3)和苯基(2,3,4,6-四-O-特戊酰基)-1-硫代-β-D-吡喃半乳糖苷 S-氧化物(5)。然后,这些糖基供体分别与芴甲氧羰基-反式-4-羟基-L-脯氨酸烯丙基酯(7)反应。糖基化反应是在 2,6-二叔丁基-4-甲基吡啶存在下,以三酸酐为促进剂,于 -70°C 温度下进行的。在过苄基亚砜供体(3)的情况下,主要产物为 Na-芴甲氧羰基-反式-4-羟基-4-O-[(2,3,4,6-四-O-苄基)-a-D-吡喃半乳糖基]-L-脯氨酸烯丙基酯(8a)。在二氯甲烷中,a-β 的比例为 3:1,在甲苯中提高到 5:1,总产率为 41%。在过新戊酰化亚砜供体(5)的情况下,Na-芴甲氧羰基-反式-4-羟基-4-O-[(2,3,4,6-四-O-新戊酰基)-β-D-吡喃半乳糖基]-L-脯氨酸烯丙基酯(9)作为唯一的糖苷产物被获得,收率为 46%。

  • AuCl3-AgOTf promoted O-glycosylation using anomeric sulfoxides as glycosyl donors at room temperature
    作者:Ashokkumar Palanivel、Ande Chennaiah、Sateesh Dubbu、Asadulla Mallick、Yashwant D. Vankar

    glycosyl donors using AuCl3/AgOTf reagent system has been described. Under optimal reaction conditions, both armed and disarmed glycosyl sulfoxide donors were found to react with a range of primary, secondary, and tertiary alcohol acceptors, and sugar derived glycosyl acceptors to afford the corresponding glycosides in moderate to good yields with predictable selectivity. The reactions are quick (20-60 min)

    Separation of the diastereomers of glycosyl sulfoxides differing in the sulfur chirality has been difficult. This article presents a fast and scalable method for their diastereoseparation using a chiral stationary phase. The usefulness of this method was demonstrated in a 500‐mg scale separation within 20 min, and in the separation of trisaccharyl sulfoxide diastereomers. Chirality 28:534–539, 2016.

  • Synthesis of methylene bridged C-disaccharides
    作者:Bernd Giese、Monika Hoch、Clemens Lamberth、Richard R. Schmidt

    日期:1988.1
    Addition of glycosyl radicals to the α-methylene lactones 8 obtained from the corresponding glycopyranosyl phenylsulfoxides 5a,b in convenient two step procedures provides methylene bridged C-disaccharides in high diastereoselectivities. Thus, after reduction of the lactone moiety the methylene bridged analogs 9–11 of kojibiose, ristobiose, and α-L-fucopyranosyl (1→2)-D-galactose, respectively, were

  • Studies on the Stereoselective Synthesis of <i>C</i>-Allyl Glycosides
    作者:Glenn J. McGarvey、Christopher A. LeClair、Bahar A. Schmidtmann
    DOI:10.1021/ol801710s
    日期:2008.11.6
    An investigation was carried out to explore the use of sulfoxide donors as common precursors to stereoisomeric C-glycoconjugates of glycoprotein and glycolipid tumor antigens. A study focusing on the effects of reaction conditions and substrate structure on the stereoselectivity of allylation was carried out. Although conditions were realized to selectively afford alpha-allylation products in good to excellent yields, the search for conditions favoring beta-selectivity proved less successful.
