  • Stereoselective Glycal Fluorophosphorylation: Synthesis of ADP-2-fluoroheptose, an Inhibitor of the LPS Biosynthesis

    describes the synthesis of a fluorinated analogue of ADP-L-glycero-beta-D-manno-heptopyranose, the donor substrate of the heptosyl transferase WaaC, which catalyzes the incorporation of this carbohydrate into LPS. Synthetically, the key step for the preparation of ADP-2F-heptose is the simultaneous and stereoselective installation of both the fluorine atom at C-2 and the phosphoryl group at C-1 through a

  • Diastereoselectivity in the synthesis of <scp>D</scp>-glycero-<scp>D</scp>-aldoheptoses by 2-trimethylsilylthiazole homologation from hexodialdo-1,5-pyranose derivatives

    日期:1994.1.1

    An exploration of the synthesis of D-glycero-D-altro-heptose, a constitutent of O antigen chains in lipopolysaccharides from Campylobacter jejuni serotypes O:23 and O:36 led to a study of the 2-trimethylsilylthiazole homologation procedure for heptose synthesis. In contrast to the diastereoselective formation of a 1,2:3,4-di-O-isopropylidene-D-glycero-α-D-galacto-heptopyranose derivative from 1,2:3,4-di-O-isopropylidene-α-D-galacto-hexodialdo-1,5-pyranose, methyl 2,3,4-tri-O-benzyl-D-hexodialdo-1,5-pyranosides with the gluco and manno configurations showed no preference for the formation of compounds with the D-glycero configuration. Attempts to achieve high diastereoselectivity in the conversion of L-glycero into the D-glycero isomers by oxidation at C-6 followed by reduction with L-selectride were unsuccessful with the thiazole adducts, but the desired products were formed in similar reactions of methyl 2,3,4-tri-O-benzyl-7-O-tert-butyldimethylsilyl-D-heptopyranosides. The approach to homologation in the altro series was thwarted by epimerization at C-5 in the attempted formation of methyl 2,3,4-tri-O-benzyl-α-D-altro-hexodialdo-1,5-pyranoside. The successful synthesis of methyl D-glycero-α-D-altro-heptopyranoside from methyl α-D-glucopyranoside was achieved by homologation followed by configurational alteration from the D-gluco to the D-altro series.

    对Campylobacter jejuni血清型O:23和O:36脂多糖O抗原链成分D-glycero-D-altro-heptose合成方法的探索,引导了对2-三甲基硅基噻唑同系化方法在庚糖合成中应用的研究。与从1,2:3,4-二-O-异亚丙基-α-D-半乳糖-己醛糖-1,5-吡喃糖形成1,2:3,4-二-O-异亚丙基-D-甘油-α-D-半乳糖-庚吡喃糖衍生物的差向异构选择性形成相比,具有葡萄糖和甘露糖构型的甲基2,3,4-三-O-苄基-D-己醛糖-1,5-吡喃糖苷在形成D-甘油构型化合物方面没有表现出偏好。尝试通过C-6氧化后用L-选择性还原剂将L-甘油转化为D-甘油异构体,在噻唑加合物中未能实现高差向异构选择性,但在甲基2,3,4-三-O-苄基-7-O-叔丁基二甲基硅基-D-庚吡喃糖苷的类似反应中形成了所需产物。在altro系列中进行同系化的方法因在尝试形成甲基2,3,4-三-O-苄基-α-D-altro-己醛糖-1,5-吡喃糖苷时C-5的差向异构化而受阻。从甲基α-D-葡萄糖苷成功合成了甲基D-甘油-α-D-altro-庚吡喃糖苷,通过同系化后从D-葡萄糖系列到D-altro系列构型改变实现。

We report the synthesis of a series of D‐glycero‐D‐manno‐heptopyranose 7‐phosphate (H7P) analogues and their inhibition properties against the isomerase GmhA and the the kinase HldE, the two first enzymes of the bacterial heptose biosynthetic pathway.
