    Carbohydrate Homologation by the Use of 2-(Trimethylsilyl)thiazole. Preparative Scale Synthesis of Rare Sugars:  l-Gulose, l-Idose, and the Disaccharide Subunit of Bleomycin A2
    摘要:
    The well established one-carbon homologation method of protected monosaccharides employing 2-(trimethylsilyl)thiazole (2-TST) as a formyl anion equivalent has been used for high yield and multigram scale synthesis of the title rare hexoses from L-xylose. Thus, L-gulose has been obtained by stereoselective anti-addition of 2-TST to aldehydo-L-xylose diacetonide followed by thiazole to formyl conversion of the resulting alcohol. The inversion of configuration at C-1 of this alcohol by an oxidation-reduction sequence prior to the aldehyde releasing from thiazole led to L-idose. The same alcohol was readily elaborated into 1,3,4,6-tetra-O-acetyl-L-gulopyranose whose highly stereoselective glycosidation coupling with 3-O-carbamoyl-2,4,6-tri-O-acetyl-alpha-D-mannosyl diethyl phosphate afforded the same peracetylated disaccharide subunit employed by Boger and Honda in the total synthesis of the antibiotic bleomycin A(2).

    摘要:
    通过使各种单糖与乙硫醇在3 mol%溴化二甲基ulf溴化物(BDMS)的存在下,在0-5℃下反应,可以以很高的收率制得各种糖类的二乙基二硫缩醛。类似地,也可以得到二丙基二硫缩醛衍生物在相同的反应条件下,使用丙硫醇可得到良好的收率。这些二硫缩醛衍生物的特征在于,使用硅胶负载的高氯酸进行过O-乙酰化。本方案的显着特征是良好至优异的收率,温和,清洁和无溶剂的反应条件。该方法非常适合大规模制备各种糖的二硫缩醛衍生物。

  • 4-(D-arabino-tetrahydroxybutyl)-4-thiazoline-2-thione synthesis of optical isomers and analogs
    作者:W.J. Humphlett

    日期:1968.8
    Abstract The previously reported 6 , unequivocal synthesis of the title compound ( 5a ) afforded a general method for the preparation of 4-substituted 4-thiazoline-2-thiones derived from fully acetylated α-halo ketoses. Such use of the α-halo ketoses ( 1b ) or ( 2b ) (as outlined in Method I of the Scheme) led to the crystalline L enantiomorph ( 5b ) that, on cocrystallization with 5a , gave the DL
    摘要先前报道的6的标题化合物(5a)的明确合成为制备由完全乙酰化的α-卤代酮糖衍生的4-取代的4-噻唑啉-2-酮提供了一般方法。α-卤代酮糖(1b)或(2b)的这种使用(如方案的方法I所述)导致结晶的L对映体(5b),与5a共结晶时得到DL形式(5c)。通过使用α-酮糖(1d-1f),该方法的进一步应用分别产生了无定形,高溶解度的D-xylo,L-xylo(粗制)和D-葡萄糖类似物5d-5f。类似地从α-酮糖(1g)获得的半乳糖-1,4-双-(4-噻唑啉-2-酮)类似物(5g)是结晶的,高熔点的并且高度不溶的。通过修改程序(方法II),用由二硫化碳甲胺4-氨基丁酸衍生的二氨基甲酸盐处理α-酮糖(1h-1i),分别导致结晶4-噻唑啉-2-酮(5h-5i),在N-杂原子上也被取代。报告了这些合成中的中间体。
  • Synthesis of sugar-glutarimide combinations

    DOI:10.1139/v92-208
    日期:1992.6.1

    Several sugar glutaramide combinations, wherein the aldehyde group of the sugar was incorporated as C-4 of the imide ring, were prepared to provide molecules with chemotherapeutic potential. The most interesting bioassay results were seen in the inhibition of the bacteria Mycobacteriumintracellularae by the glutarimide combinations with D- and L-xylose.
