    以 3,6-二氢-2H-1,2-恶嗪为关键反应的硼氢化反应立体选择性合成氮杂、氨基和亚氨基糖衍生物
    摘要:
    从对映体纯 3,6-dihydro-2H-1,2-oxazinessyn-1 开始,我们通过标准的硼氢化/氧化方案以立体选择性的方式引入了一个额外的羟基。在“常规”条件下,底物控制足以实现非常高的立体选择性。然而,当使用部分“降解”的硼烷试剂时,会分离出非对映体产物。我们可以通过向“新鲜”硼氢化试剂中添加醇来有意合成这种新的非对映异构体。立体诱导的水平随着添加醇的空间体积而增加:MeOH < nBuOH < iPrOH < tBuOH。经过两步氧化/还原序列后,可以获得另一个 5-羟基-1,2-恶嗪差向异构体。得到的5-羟基-1,2-恶嗪非对映异构体 2 在一系列转化中用作通用中间体,从而产生多种氨基多元醇衍生物。两种非对映异构体的完全脱保护而不断裂 N-O 键导致了新型多羟基化四氢-2H-1,2-恶嗪 3 和外延 3。通过改变脱保护条件,可以得到具有 D-艾杜醇构型的开链氨基多元醇 4。在替代序列中,5-羟基-1

  • β-Alkoxy-γ-amino Aldehydes by Internal Redox Ring Cleavages of Carbohydrate-Derived Enantiopure 1,2-Oxazines and Preparation of Heterocycles with Aminopolyol Side Chain

    N-Methylation of syn- or anti-configured 3,6-dihydro-2H-1,2-oxazines and subsequent treatment with triethylamine smoothly provided enantiopure α,β-unsaturated β-alkoxy-γ-amino aldehydes bearing different protected diol, triol, or tetrol side chains in good to excellent yields. The N-O bond cleavage occurs under mild conditions and involves an internal redox process. The method is also applicable to tetrahydro-2H-1,2-oxazines, which either lead to 4-amino ketose or aldose derivatives (d-sorbose or d-idose configuration). The equivalency of the generated β-alkoxyenal moiety with 1,3-dicarbonyl compounds could be demonstrated by condensation reactions with hydrazine or 2-aminoimidazole derivatives providing a series of new pyrazole or imidazo[1,2-a]pyrimidine derivatives with stereodefined and protected aminopolyol side chains.

  • Synthesis of Enantiopure Functionalized β-Alkoxy γ-Amino Aldehydes by a New Internal Redox Ring Cleavage of Carbohydrate-Derived 1,2-Oxazines

    N-Methylation of 3,6-dihydro-2H-1,2-oxazines such as syn-1 or anti-1 followed by treatment with triethylamine smoothly furnished enantiopure β-alkoxy γ-amino aldehydes syn-2 and anti-2 in excellent yields. This mild N-O bond cleavage may be classified as internal redox process. Similar transformations of related 1,2-oxazines led to the expected compound anti-6 or to protected 4-amino hexose derivative 10. Starting from syn-2 or anti-2 condensation with hydrazine afforded new pyrazole derivatives syn-11 and anti-11 with stereodefined and protected amino diol side chain. ­Heterocycles syn- 12 and syn-13 were prepared from syn-2 by condensation with 2-aminoimidazole or 2-aminobenzimidazole, respectively.
    将 3,6-二氢-2H-1,2-噁嗪(如 syn-1 或 anti-1)进行 N-甲基化,然后用三乙胺处理,就能以极好的收率顺利制得对映纯δ-²-烷氧基δ-³-氨基醛 syn-2 和 anti-2。这种温和的 N-O 键裂解可归类为内部氧化还原过程。相关的 1,2-噁嗪类化合物经过类似的转化后,可得到预期的化合物 anti-6 或受保护的 4-氨基己糖衍生物 10。从 syn-2 或 anti-2 开始,与肼进行缩合,可得到具有立体定向和受保护氨基二元醇侧链的新吡唑衍生物 syn-11 和 anti-11。由 syn-2 通过与 2-氨基咪唑或 2-氨基苯并咪唑缩合,分别制备出了杂环 syn- 12 和 syn-13。
  • Acid-Mediated Transformations of Enantiopure 3,6-Dihydro-2H-1,2-oxazines into Functionalised Aminotetrahydrofuran Derivatives
    作者:Hans-Ulrich Reissig、Vjekoslav Dekaris、Bettina Bressel
    DOI:10.1055/s-0029-1218532
    日期:2010.1
    Two new routes to substituted aminotetrahydrofuran derivatives have been investigated. Treatment of 3,6-dihydro-2H-1,2-oxazines with hydrochloric acid in the presence of zinc provided 4-benzylamino-5-hydroxy furanose derivatives which contain a quaternary anomeric centre with a vinyl unit. Upon mesylation and subsequent heating in aqueous media 5-hydroxy-3,4,5,6-tetrahydro-1,2-oxazines were converted into novel bicyclic 1,2-oxazines with complete regio- and stereoselectivity. Cleavage of the N-O bond and subsequent debenzylation furnished enantiopure polyhydroxylated aminotetrahydrofuran derivatives which are promising ligands for selectin inhibition studies.
    我们研究了两种获得取代氨基四氢呋喃衍生物的新途径。在锌存在下,用盐酸处理 3,6-二氢-2H-1,2-噁嗪,可得到 4-苄基氨基-5-羟基呋喃糖衍生物。在水介质中,5-羟基-3,4,5,6-四氢-1,2-噁嗪经甲基化并随后加热后,以完全的区域和立体选择性转化为新型双环 1,2-噁嗪。N-O 键的裂解和随后的去苄基化反应生成了对映体纯的多羟基氨基四氢呋喃衍生物,这些衍生物是很有希望用于选择素抑制研究的配体。

    utilised to synthesise imino sugars (polyhydroxylated pyrrolidines). Samarium diiodide induced cleavage of the 1,2-oxazine N–O bond furnished 1,4-amino alcohols, which were cyclised to give the corresponding pyrrolidine derivatives after activation by mesyl chloride. This sequence either led to a 3-methoxy-substituted trihydroxylated pyrrolidine derivative or to the related fully deprotected compound.
