    Dehydroamino acid derivatives from D-arabinose and L-serine: synthesis of models for the azinomycin antitumor antibiotics
    摘要:
    Synthesis of aldehydes 17 from D-arabinose and 31 from L-serine provided key precursors for the generation of highly functionalized dehydroamino acid derivatives upon condensation with glycyl phosphonates. Subsequent bromination and intramolecular addition/elimination afforded the azabicyclo[3.1.0]hex-2-ylidene ring system postulated to exist in the azinomycin antitumor antibiotics.

    Stereoselective preparation of O-alkoxy d-tetrose, d-pentose, 2-deoxy-d-glycero tetrose and 2,3-dideoxy-d-erythro pentose derivatives by an iterative elongation of 2,3-O-isopropylidene-d-glyceraldehyde
    摘要:
    All D-pentoses are synthesized by one-carbon chain elongation commencing with the addition of the lithium salt of ethyl ethylthiomethyl sulfoxide to 2-O-(t-butyldimethylsilyl)-3,4-O-isopropylidene-D-erythrose and D-threose, 16 and 17. The addition of the above-mentioned nucleophile to 2-deoxy-3,4-O-isopropylidene-D-glycero tetrose, 19, gave rise to 2,3-dideoxy-D-glycero pentose. The starting aldehydes, 16, 17 and 19, are easily available from 2,3-O-isopropylidene-D-glyceraldehyde, 1, and ethyl ethylthiomethyl sulfoxide. (C) 1999 Elsevier Science Ltd. All rights reserved.

  • Kinetic cyclohexylidenation and isopropylidenation of aldose diethyl dithioacetals

    Abstract Aldose diethyl dithioacetals react with 1.2 equivalents of 1-ethoxycyclohexene or 2-methoxypropene in N , N -dimethylformamide at 0° with p -toluenesulfonic acid as catalyst to give the five-membered ring acetal attached to the two terminal oxygen atoms as the major product in every case. In most instances, a small proportion of the terminal, six-membered ring acetal was also obtained, and
    摘要醛糖二乙基二硫缩醛在对甲苯磺酸的催化下于0°N下与1.2当量的1-乙氧基环己烯或2-甲氧基丙烯在N,N-二甲基甲酰胺中反应,制得与两个末端氧原子相连的五元环缩醛在每种情况下都是产品。在大多数情况下,还可以获得一小部分的末端六元环缩醛,在少数情况下,也可以分离出末端的七元环缩醛。在室温下环己基化可得到相同的产物,但在室温下异丙基-亚基化在某些情况下会导致部分重排。环己基化反应产生较小比例的次要六元和七元环产物。由13 Cn.mr和质谱确定结构。13 Cn.mr 发现模型环己叉基衍生物的光谱与先前研究的异丙叉基衍生物的光谱非常相似。当将前体二醇的光谱与两种衍生缩醛的光谱进行比较时,注意到了两个对结构确定有用的新特征。1,3-丙二醇衍生物的C-2的化学位移在乙缩醛化作用下向高场移动了6-9 ppm,并且根据缩醛的类型和形成的环大小,与氧连接的二醇碳原子的移位受到影响。对于亚甲基缩醛也有类似的

    cyclohexenamide moiety. It has been determined that the intermediate in conversion of this type is an oxazolinium-5-one (munchnone) that reacts with many nucleophiles to yield the products above. The munchnone can also undergo cycloaddition with acetylenic dipolarophiles to form pyrroles. Through internal nucleophilic attack, Ugi products are shown to convert to a protected monosaccharide derivative and to 1,4-benzodiazepine-2
    引入了“通用异氰化物”的概念,可以对 Ugi 四组分缩合产物进行后缩合改性。该策略适用于文库的合成。通过在 Ugi 反应中使用 1-异氰基环己烯作为异氰化物输入,产物环己烯酰胺可以转化为多种产物。从最初的 α-(酰氨基)酰胺,新的羧酸、酯和硫酯通过环己烯酰胺部分的酸活化转化产生。已经确定这种类型的转化中间体是恶唑啉鎓-5-酮(munchnone),它与许多亲核试剂反应产生上述产物。munchnone 还可以与炔属偶极亲和试剂发生环加成反应,形成吡咯。通过内部亲核攻击,Ugi 产品显示可转化为受保护的单糖衍生物和 1,4-苯二氮卓-2,5-二酮。所描述的所有转换都包含一个步骤。Ugi产品的树脂捕获是恶魔...

    摘要研究了一些醛糖二乙基二硫缩醛在N,N-二甲基甲酰胺中的酸催化端基-O-异亚丙基衍生物的重排。d-阿拉伯糖和d-木糖二乙基二硫缩醛的4,5-O-异亚丙基衍生物分别重排至2,3-和2,3-和3,4-和3,4-O-异亚丙基衍生物的混合物。d-半乳糖,d-甘露糖和d-葡萄糖的5,6- O-异亚丙基衍生物重新排列为4,5、3,4-和2,3-和3,4-O的混合物-异亚丙基衍生物。通过交叉实验,并考虑到所得产物的结构和重排速率,这些重排显示为分子内。3,还可以直接从d-甘露糖二乙基二硫缩醛制备4-O-异亚丙基-d-甘露糖二乙基二硫缩醛。产物与起始物质的比例一致表明,4,5-反式-二取代的2,2-二甲基-1,3-二氧戊环产物比4-取代的2,2-二甲基-酯稳定约1.2 kcal.mol -1。 1,3-二氧戊环原料。在高浓度和低浓度酸的存在下,d-葡萄糖二乙基二硫缩醛与过量的2-甲氧基丙烯反应,主要得到2

    Acetonation of the diethyl dithioacetals of D- and L-arabinose gives the corresponding 2,3:4,5-diisopropylidene acetals (2a and 2b) as oils having [alpha]D +82 and -81 degrees, respectively; in admixture, the enantiomers form a well crystallized racemate, m.p. 43-45 degrees. The initial product of acetonation is the 4,5-monoisopropylidene acetal. Demercaptalation of 2a with mercury(II) chloride-cadmium
    D-和L-阿拉伯糖的二乙基二硫缩醛的乙酰化分别得到相应的2,3:4,5-二异亚丙基缩醛(2a和2b),其为αD+82和-81度的油;在混合物中,对映异构体形成结晶良好的外消旋体,mp 43-45度。丙酮化的初始产物是4,5-单异亚丙基乙缩醛。用氯化汞(II)-碳酸镉对2a脱巯基化反应可高产率获得2,3:4,5-二-O-异亚丙基-醛-D-阿拉伯糖(5),但文献报道的方法使用氯化汞(II)-氧化汞(II)可提供5和1,2:3,4-二-O-异亚丙基-β-D-阿拉伯吡喃葡萄糖(6)的混合物。痕量的酸可将醛衍生物5完全完全转化为环状二缩醛6。
  • Preparation of 2,5-Anhydrohexitols (Part I). Silicon-Directed Stereocontrolled Cyclization
    作者:Floris L. van Delft、A. Rob、P.M. Valentijn、Gijs A. van der Marel、Jacques H. van Boom
    DOI:10.1080/07328309908543989
    日期:1999.1.1
    Stereoselective chain-extension of carbohydrate aldehydes with the hydroxymethylating reagent (dimethylphenylsilyl)methylmagnesium chloride (1) followed by acid-mediated cyclization gives access to 2,5-anhydro-hexitols. The stereoselectivity of the ring closure depends on the nature of the acid, i.e., treatment with excess BF3. Et2O or catalytic H2SO4 leads to tetrahydrofurans with 2,3-cis or 2,3-trans configuration, respectively. Concomitant elimination is effectively suppressed in case of cyclisation of the more sterically hindered isopropyl substituted silanes.
