  Short Synthesis of Enantiopure C₂-Symmetric 1,2:4,5-Diepoxypentane and “Pseudo”-C₂-Symmetric 3-Azido-1,2:4,5-diepoxypentane from Arabitol

  摘要：

  On the basis of our previously described selective protection of arabitol as its 1,2:4,5-bis-pentylidene acetal 5, we report a straightforward synthesis of the novel "pseudo"-C-2-symmetric 3-azido-1,2:4,5-diepoxypentane building block 4 in 6 steps from arabitol. Using a similar synthetic route, an improved synthesis of the C-2-symmetrical 1,2:4,5-bis-epoxypentane building block I is described, also in 6 steps from arabitol. Both enantiomers of 1 and 4 are accessible, and all reactions involved are easily amenable for large-scale synthesis.

• The Synthesis of AraBOX, a New 4,4′-Bis(oxazoline), from Novel Pentitol-Derived Bis-β-amino Alcohols

  phenyl 4,4'-bis(oxazoline) [AraBOX] is described. The novel ligand is prepared in two efficient steps from a bis-[(O-silyl)β-amino alcohol], via conversion into an intermediate bis(benzamide) followed by a one-pot deprotection-activation-ring closure (DARC) oxazoline formation. To our knowledge, this is the first reported synthesis of an oxazoline ring via this DARC method. The synthesis of two precursor

  描述了新型苯基 ​​4,4'-双(恶唑啉) [AraBOX] 的制备。新型配体由双-[(O-甲硅烷基)β-氨基醇]通过两个有效步骤制备，通过转化为中间体双（苯甲酰胺），然后是一锅脱保护-活化-闭环（DARC）恶唑啉形成。据我们所知，这是首次报道通过这种 DARC 方法合成恶唑啉环。还描述了两种前体双-β-氨基醇的合成，(2R,4R)-和 meso-2,4-diaminopentane-1,5-diol，分别衍生自 D-(+)-arabitol 和木糖醇.
