  A concise route to phytosphingosine from lyxose

  摘要：

  Phytosphingosine was synthesized from the commercially available D-2,3-O-isopropylidene-D-lyxofuranose in 28% overall yield by a six-step procedure. This procedure is expedient and flexible for introduction of other lipid moieties on the phytosphingosine structure to make a variety of derivatives that can support the further exploration of their related biological functions.

  A highly efficient synthesis of unnatural l-sugars from d-ribose

  摘要：

  A preparative and short synthesis of L-ribose and L-apiose was accomplished starting from D-ribose via stereoselective cis-dihydroxylation and C2-hydroxymethylation, respectively. These L-sugars can serve as versatile intermediates for the synthesis Of L-nucleosides. (c) 2005 Elsevier Ltd. All rights reserved.

  aminomethyl C-3 substituted l-fuco-azafagomine and of its C-6 epimer from d-lyxose is reported. The key step of the synthesis is the introduction of the biimino (–NH–NH–) moiety by reductive hydrazination of a 1-deoxy-ketohexose with tert-butyl carbazate. The 3-aminomethyl-azafagomine derivatives were used as lead compounds in the generation of libraries of novel types of derivatives by attaching different

  据报道，由d -lyxose合成了一种新的氨基甲基C-3取代的1 - fuco- azafagomine及其C-6差向异构体。合成的关键步骤是通过1-脱氧酮己糖与氨基甲酸叔丁酯的还原酰化作用引入biimino（–NH–NH–）部分。通过氨基键将不同的疏水基团连接到氨甲基取代基上，将3-氨甲基-氮杂花胺衍生物用作新型化合物文库中的先导化合物。这些多羟基化的六氢哒嗪可被视为一种新型的重氮-C具有biimino（–NH–NH–）部分的-g-糖苷类似物。还报道了合成的所有新的C-3取代的氮杂花菁的构象分析和糖苷酶抑制特性。具有1 - fuco构型的那些已经显示出对α- 1-岩藻糖苷酶的选择性抑制。

  A divergent approach has been developed for the synthesis of some important iminosugars by stereoselective allylation of the lyxosylamine derived from d -lyxose and intramolecular 5- exo -tet ring opening of the epoxide. The strategy described in this paper will be useful for the synthesis of some other biologically active iminosugars for the drug-discovery program.

  Two new biotin analogues, biotin carbonate 5 and biotin carbamate 6, have been synthesized. These molecules were designed to reversibly bind with streptavidin by replacing the hydrogen‐bond donor NH group(s) of biotin’s cyclic urea moiety with oxygen. Biotin carbonate 5 was synthesized from L‐arabinose (7), which furnishes the desired stereochemistry at the 3,4‐cis‐dihydroxy groups, in 11 % overall

  已经合成了两种新的生物素类似物，碳酸生物素5和氨基甲酸酯6。通过将生物素的环状脲部分的氢键供体NH基团替换为氧，这些分子可与链霉亲和素可逆结合。碳酸生物素5是由L阿拉伯糖（7）合成的，它在3,4-顺式-二羟基基团上具有所需的立体化学，总产率为11％（十个步骤）。氨基甲酸酯类生物素6的合成是由L-半胱氨酸衍生的手性醛33完成的总收率11％（分7步）。水溶性生物素碳酸盐类似物的表面等离子共振分析46和生物素类似物氨基甲酸酯47表明ķ d结合链霉亲和这些化合物的值分别为6.7×10 -6 中号和1.7×10 -10 中号，分别。这些值显着大于生物素的值（K D = 10 -15  M），因此表明氮原子对于生物素与链霉亲和素之间的强结合的重要性。
