  Preparation of Di-altro-.BETA.-cyclodextrins with Two Altrosides as the Macrocyclic Units through Selective Synthesis of Regioisomers of Di(2-0-mesitylenesulfonyl)-.BETA.-cyclodextrin.

  摘要：

  与报告中使用氧化二丁基锡/三乙胺/对甲苯磺酰氯的方法相比，合成二(2-O-甲磺酰基)-β-环糊精 2-4 的摄取异构体的产率提高了 3、4 倍。由 2-4 制备出二甘露聚氧乙烯醚-β-环糊精的 Regioisomers 5-7，并分别转化为相应的以两个altrosides 作为大环单元的二altro-β-环糊精（8-10）。通过核磁共振研究了二-对半-β-环糊精中altroside部分的构象，发现altroside会根据其是否为大环成员以及在环中的位置而改变其构象。

  Regioselective 2A,2D-disulfonyl capping of β-cyclodextrin for practical bifunctionalization on the secondary hydroxyl face

  摘要：

  A useful technique to bifunctionalize the secondary hydroxyl face of P-cyclodextrin is described. Regioselective 2(A),2(D)-disulfonylation of beta -cyclodextrin was achieved by reacting P-cyclodextrin with a combination of a novel disulfonyl imidazole reagent and molecular sieves in DMF. The resulting disulfonate was converted to 2(A),3(A),2(D),3(D)-dimannoepoxy-beta -C, cyclodextrin and 3(A),3(D)-diamino-3(A),3(D)-dideoxy-(2(A) S,3(A)S) (2(D)S,3(A)S)-beta -cyclodextrin, which contains two functional groups on the periphery of the molecule.

  attack by 3X−1-OH at the 2X-C position of the epoxide is observed. The reaction affords the apparent trans-diequatorial products and ensures an efficient construction of fused heterocycles within the cyclodextrin belt. In the case of 2I,3I:2II,3II-di-manno-epoxy-β-cyclodextrin, a tandem-type reaction is initiated by the attack by the 3VII-OH group at the 2I-C position to generate a fused pentacycle

  在 2X,3X-甘露糖环氧化物的亲核开环反应中，进入的亲核试剂几乎完全攻击环氧化物的 3X-C 位置。然而，当分子内羟基充当亲核试剂时，观察到非常不寻常但非常有趣的反向区域选择性，即仅观察到 3X-1-OH 在环氧化物的 2X-C 位置处的攻击。该反应提供明显的反式二赤道产物并确保在环糊精带内有效构建稠合杂环。在 2I,3I:2II,3II-di-manno-epoxy-β-cyclodextrin 的情况下，串联型反应由 2I-C 位置的 3VII-OH 基团的攻击引发，生成稠合的五环。(© Wiley-VCH Verlag GmbH & Co.

  A practical and convenient method for the preparation of α-, β-, and γ-cyclodextrin derivatives, in which the secondary hydroxyl faces of A- and C-glucose units are regioselectively modified, has been developed. Reactions of α-, β-, and γ-cyclodextrins with 1,4-dibenzoylbenzene-3′,3″-disulfonyl imidazole in N,N-dimethylformamide in the presence of molecular sieves regioselectively afforded the corresponding
