  Acetal chlorination with MnO2-Trimethylchlorosilane

  摘要：

  alpha-Chloroacetals am obtained in almost quantitative yields, by treating acetals with MnO2-trimethylchlorosilane in CH3OH:CH3CN (1:1). The halogenation is explained by a ligand-transfer process on an enolether intermediate, mediated by a Mn(IV)-chloride species.

  α-Hydroxyaldehyde dimethyl acetals are prepared efficiently by conversion of α-haloaldehyde dimethyl acetals into α-haloaldehyde hemiacetal acetates and subsequent methanolysis promoted by lithium methoxide.

  通过将α-卤代醛二甲基缩醛转化为α-卤代醛半缩醛乙酸酯并随后通过甲醇锂促进甲醇分解，可有效地制备α-羟基醛二甲基乙缩醛。

  日期：1994.1

  2-Chloro acid methyl esters were prepared in good yields treating 2-chloro aldehyde dimethyl acetals with trichloroisocyanuric acid in DMF. Aldehyde dimethyl acetals with the 2-halogen on a tertiary carbon atom were poorly reactive and could be oxidized effeciently only after their transformation into 1,3-dioxolanes.

  2-氯酸甲基酯通过在DMF中用三氯异氰尿酸处理2-氯醛二甲基缩醛制备，产率良好。含有2-卤素的醛二甲基缩醛在三级碳原子上的反应活性较差，仅在转化为1,3-二氧杂环戊烷后才可有效氧化。

  A conserved inner-core oligosaccharide epitope expressed on the lipopolysaccharide (LPS) of a range of disease causing pathogenic bacterial isolates, including Actinobacillus pleuropneumoniae (Ap), Mannheimia haemolytica (Mh) and Pasteurella multocida (Pm), is disclosed. Construction of a mutant bacterial strain exclusively expressing the conserved inner core OS epitope as a terminally exposed structure has allowed the identification, production and isolation of an inner core LPS which is common to all three organisms. Further provided are associated vaccines, antibodies raised against the conserved LPS inner core and glycoconjugates comprising the LPS inner core linked to an immunogenic carrier.

  本文披露了一种保守的内核寡糖表位，该表位表达在一系列致病细菌分离物的脂多糖（LPS）上，包括副猪咳嗽杆菌（Ap）、血色素单胞菌（Mh）和多杀性巴氏杆菌（Pm）。构建一种突变的细菌菌株，该菌株仅表达保守的内核OS表位作为末端暴露结构，使得可以鉴定、生产和分离所有三种生物体共有的内核LPS。此外，还提供了相关的疫苗、针对保守的LPS内核产生的抗体以及将LPS内核与免疫原载体连接的糖偶联物。
