  Stereocontrolled introduction of an amino group at C-6 of d-galactose via (3,3)-sigmatropic rearrangements—novel synthesis of lincosamine and 7-epi-lincosamine precursors

  摘要：

  A new and stereoselective route to the aminoglycoside components of the antibiotics lincomycin and clindamycin is presented, The key step involves diastereoselective introduction of the amino group at C-6 of D-galactose by (3,3)-sigmatropic rearrangements of the corresponding allylic (Z)-trifluoroacetimidate and (Z)- and (E)-allylic thiocyanates. Epoxidation of the resulting trifluoroacetamide with m-CPBA led to the epoxide with high threo-selectivity. (C) 2000 Elsevier Science Ltd. All rights reserved.

• Approaches to the Synthesis of Lincosamine, a Derived Portion of the Antibiotic Lincomycin

  A variety of approaches towards the synthesis of lincosamine, a derived portion of the antibiotic lincomycin , are reported. Initial approaches involved the intramolecular delivery of a nitrogen atom ( trichloroacetimidate , trichloroacetylcarbamate , carbamate, 2-amino-2- phenylacetate ) attached to O4 onto C6 of a 6,7-anhydrooctoside. Later approaches, albeit more direct but again largely unsuccessful, involved the Sharpless titanium(IV)-mediated nucleophilic opening of a suitable 6,7-anhydrooctose, and the Sharpless oxyamination and the aziridination of suitable octenoses . As an aid to the structure elucidation of several compounds encountered in this work, single-crystal X-ray structure determinations are reported for methyl 6,7-anhydro-2,3-di-O-benzyl-8-deoxy-α-D-threo-D-galacto-octopyranoside , methyl 6,7-anhydro-2,3-di-O-benzyl-8-deoxy-α-D-threo-D-gluco-octopyranoside and 7-azido-7-deoxy-1,2:3,4-di-O-isopropylidene-β-L-erythro-Dgalacto-octose.

  据报道，合成抗生素林可霉素衍生部分林可胺的方法多种多样。最初的方法是在分子内将一个氮原子（三氯乙酰亚氨酸、三氯乙酰氨基甲酸酯、氨基甲酸酯、2-氨基-2-苯基乙酸酯）连接到 6,7-脱水辛糖苷的 C6 的 O4 上。后来的方法（虽然更直接，但基本上也不成功）包括由 Sharpless 钛（IV）介导的合适的 6,7-anhydrooctose 的亲核开路，以及合适的辛烯糖的 Sharpless 氧化和叠氮化。为了帮助阐明这项工作中遇到的几种化合物的结构，报告了甲基 6,7-anhydro-2,3-di-O-benzyl-8-deoxy-α-D-threo-D-galacto-ctopyranoside 、甲基 6,7-anhydro-2,3-di-O-benzyl-8-deoxy-α-D-threo-D-gluco-ctopyranoside 和 7-azido-7-deoxy-1,2：3,4-二-O-异亚丙基-β-L-赤式-D-半乳糖苷。

  Abstract The stereochemistry of the major osmylation products of carbohydrate-based allylic alcohols can usually be predicted by application of Kishi's empirical rule. In particular, the addition of OsO 4 can be formulated as taking place in the more abundant conformation on the surface anti to a pyranose or furanose ring-oxygen atom located at a stereocentre adjacent to the olefinic linkage. Exceptions

  摘要通常可以通过使用Kishi的经验规则来预测基于碳水化合物的烯丙基醇的主要渗透产物的立体化学。特别地，OsO 4的添加可以配制成在表面上相对于位于邻近烯键的立体中心的吡喃糖或呋喃糖环-氧原子更丰富的构象发生。共轭羰基化合物有时会遇到Kishi的同化作用经验规律的例外情况。

  Methyl (E)-2,3-di-O-benzyl-6,7,8-trideoxy-α-D-galacto-oct-6-enopyranoside, a potential precursor to lincosamine, has been prepared from both methyl α-D-galactopyranoside and methyl α-D-glucopyranoside, with the required inversion at C4 in the latter sequence being effected by a conventional oxidation-reduction. As well, (E)-6,7-dideoxy-1,2: 3,4-di-O-isopropylidene-α-D-galacto-oct-6-enose and (E)- and (Z)-6,7,8- trideoxy-1,2:3,4-di-O-isopropylidene-α-D-galacto-oct-6-enose have been prepared from 1,2: 3,4-di-O-isopropylidene-α-D-galactose.

  甲基(E)-2,3-二-O-苄基-6,7,8-三脱氧-α-D-半乳糖-辛-6-烯吡喃糖苷是一种潜在的林可胺前体，已从甲基α-D-吡喃半乳糖苷和甲基α-D-吡喃葡萄糖苷中制备出来，后者序列中 C4 所需的反转是通过传统的氧化还原法实现的。此外，(E)-6,7-二脱氧-1,2:3,4-二-O-异亚丙基-α-D-半乳糖-辛-6-烯糖和(E)-和(Z)-6,7,8-三脱氧-1,2:3,4-二-O-异亚丙基-α-D-半乳糖-辛-6-烯糖也是由 1,2:3,4-二-O-异亚丙基-α-D-半乳糖制备的。
